The slope of a linear line (or a linear equation) can be found by simply taking 2 values for x and y and then using the slope formula which is [tex]\frac{dy}{dx}[/tex] or:
[tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
Example:
Let's say you're give this table:
x: 1, 2
y: 1, 2
Following the steps which I gave, you take 1 value for the y (preferably the larger one) which in this cause will be 2 and then another y from the table which would be 1
Do the same for x
Now plug the values taken in the slope formula and you get:
[tex]\frac{2 - 1}{2 - 1}[/tex]
[tex]\frac{1}{1} = 1[/tex]
Therefore the slope is 1.
Answer:
Rise/run
Rise over run.
Step-by-step explanation:
To find the slope pick two perfect spots on the line when the coordinates are not decimals.
Then, take those two points and figure out the distance. You will use rise/run.
so rise is how much you either go up or down and run is how much you either go right or left. so how much you'll go up or down? how much will you move right or left?
Lets say you have to go up 5 and then left 7 to get to the coordinate.
That's your slope! you went up so it's positive and you went left so it's negative. Rise over run : rise 5 left 7 so, 5 and -7 which is 5/-7 and that's your slope!
c - 12 = -14
and
7 + x = -1
plz help thank you
Answer: x= -2, c= -8
Step-by-step explanation: To solve the first equation, move the 12 over to the right side. To do this, do the oposite operation. So add 12 on both sides. The 12 on the left side cancels out, and you are left with x= -14+12. X=-2. Do the same thing for the next equation. Subtract 7 from the left side and the right side. C= -1-7. C= -8

5. The denominator of a fraction exceeds the numerator of a fraction by 25.
The value of the fraction is 3/8. Find the number
9514 1404 393
Answer:
15/40
Step-by-step explanation:
The difference between denominator and numerator in 3/8 is 8-3 = 5. In order to get an equal-value fraction with that difference being 25, each of the numbers must be multiplied by 5:
3/8 = 15/40
The number is 15/40.

how many bricks each 22 cm long and 15 CM broad will be required to pave a court 30 metre long and 22 wide
Answer:
BBBBBBBBBBBBBBBBBBBB
Step-by-step explanation:
CAUSE I SAID SO
Answer:
20,000 bricks
Step-by-step explanation:
length of brick(L)=22cm
breadth of brick(B)=15cm
now,
area of brick(A)=L×B
=22×15s.q.cm
=0.033s.q.m
again,
length of court(l)=30m
breadth of court(b)=22m
now,
area of court(a)=l×b
=30×22s.q.m
=660s.q.m
lastly,
no.of required brick=area of court/area of
brick
=600 s.q.m/0.033s.q.m
=20,000bricks
What is the slope of a surface having a rise of 5 feet and a run of 0 feet?
Answer: The slope is "undefined."
Step-by-step explanation: In math, division by 0 is undefined-- like you can't do it
For slope, you need to divide rise/run. If the run is 0, so undefined.
In real life, this surface would be like a wall or a door. They don't have a slope if they're constructed properly!

The wheels on Madison's bike are 64 inches in circumference. How many times do the wheels rotate if Madison rides 300 yards?
Answer:
Hello the answer is
diameter = 49cm;
radius = diameter/2 = 24.5cm;
circumference = 2πr ≈ 153.94 = 154cm

Solve the compound inequality
Answer:
4/7 > x > -11/7
Step-by-step explanation:
First, add -4/3 to all parts
then divide all parts by -7/3
so, We need to separate it into two inequalities
[tex] \frac{4 - 7x}{3} > 0[/tex]
[tex] \frac{4 - 7x}{3} < 5[/tex]
then we solve for x,
[tex] \frac{4 - 7x}{3} > 0 = x < \frac{4}{7} [/tex]
[tex] \frac{4 - 7x}{3} < 5 = x > - \frac{11}{7} [/tex]
so we ended up like this
[tex]x = ( - \frac{11}{7} \frac{4}{7})[/tex]

Lon is selling gift baskets at a craft fair. His costs are $75 for the table and $12 per basket. He sells each basket for $20.
1. Let b equal the number of baskets. Which expression represents Lon's costs? *
A- 12b - 75
B- 12b +75
C- 20b - 75
D- 20b -12b
2. How many baskets must be sold to make a profit? Solve this inequality to find out. 20b > 12b + 75 (hint: remember it's asking to make a profit) *
A- fewer than 9
B- fewer than 10
C- at least 10
D- more than 12
Answer:
1. B
2. D
Step-by-step explanation:
1. Lon's cost would be the $12 per basket times how many baskets he sells, in this case b plus the cost of the table. Lon's expression is 12b + 75
2. He needs a profit and the only way he could make that profit is if he sells more than 12.
20b > 12b + 75
20 (12) > 12 (12) + 75
240 > 140 + 75
240 > 215

solve as multi-step eqaution 24(34 + r) = 1200
The value of 'r' in the expression 24(34 + r) = 1200 is 16.
What are the basic properties of arithmetic laws of operations?There are three types of basic arithmetic laws of operation.
Commutative law for addition and multiplication states,
a + b = b + a.
a×b = b×a.
Distributive law states,
a(b ± c) = ab ± ac.
Associative law states,
a + (b + c) = (a + b) + c.
Given, An expression 24(34 + r) = 1200.
First, we'll distribute LHS,
24×34 + 24×r = 1200.
816 + 24r = 1200.
24r = 1200 - 816.
24r = 384.
r = 384/24.
r = 16.

Answer:
y = 2x + 8
Step-by-step explanation:
You can see that the line crosses the y-intercept at 8 which is point (0, 8). From that y-intercept point you rise 2 then run 1 to get to point (2, 12), this rise over run is your slope 2/1 or simply 2.
y = mx + b
m is your slope
b is your y-intercept
y = 2x + 8
