“B” is the y-intercept when x = 0. They give this in the table as “-2” so b = -2
Find slope (m) = (-8)-(-2)/(-2)-0 = 3
Equation A is y = 3x - 2 (y = mx + b)
Equation B find “m” and “b”:
Find m = (-9)-(-5)/(-3)-(-1) = 2
To find be, plug in m, x, and y from ANY coordinates in table b into y = mx + b:
-9 = 2(-3) + b
-9 = -6 + b
b = -3
Equation b is y = 2x -3
Use substitution and substitute all of equation “b” for “y” in equation a:
2x - 3 = 3x - 2
Algebra: x = -1
Plug back into equation a:
y = 3(-1) -2
y = -5
x = -1
(-1, -5) final answer (B)
Complete the equation of the line whose slope is -5/3
and y-intercept is (0, -2).
Answers
Answer:
these are tough, it takes a lot of practice to get used to these, sooo
Step-by-step explanation:
we know the slope, m= -5/3, and we're given a point so use the point slope formula
y= mx + b
the point we are given is in this form (x,y)
then plug the information into our point slope formula
y = (-5/3) x + (-2)
y = -5x/3 -2

Answer:
-x + 5y = 12
Step-by-step explanation:
Eliminate the fractional coefficient by multiplying both sides by 5:
5y - 15 = x - 3
Combine the constants: 5y = x + 12
Subtract x from both sides: -x + 5y = 12 This is in standard form

Answer:
(b) 2 years
Step-by-step explanation:
The interest formula is ...
I = Prt . . . . interest rate r on principal P for t years
We can fill in the known values and solve for t.
60 = 750·0.04·t
60/30 = t = 2
The loan was repaid in 2 years.

Answers
Answer:
eric=12
bill=16
Step-by-step explanation:
you can solve this using two simple algebraic equations. this is the key I will be using:
x=bill
y=Eric
x+y=28
x=y+4
since x is by itself in the second equation, I can replace the x in the first equation with y+4
(y+4)+y=28
subtract 4 from both sides
y+y=24
which is also 2y=24
divide both sides by two.
y=12
so now we know Eric is 12 years old.
using this, we can replace the "y" in the second original equation (x=y+4)
x=12+4
x=16
Bill is 16 years old.

Answer:
function b
Step-by-step explanation:
When its asking for which function has a greater rate of change its asking for which slope has a greater value
the slope is calculated by change in y over change in x
for function a, as y goes up 2 x goes up 1
so the slope ( rate of change) is 2/1
for function b is y goes up 3 x goes up 1
so the slope (rate of change) is 3/1
3/1 is greater than 2/1 so function b has a greater rate of change

Three corners of a city bloc is located at (2,2) (2,-4) (-5,-4) on a coordinate plane what are the coordinates of the fourth corner
Answers
Answer:
(-5, 2)
Step-by-step explanation:
Three corners of a rectangular city block are located at (2,2), (2,-4) and (-5,-4) on a coordinate plane. What are the coordinates of the fourth Coordinate?
Solution:
A rectangle is a quadrilateral (has four sides and four angles) in which opposite sides are equal and parallel. Also, all the angles are at 90 degrees.
Since the city block is rectangular in shape, therefore the fourth coordinate would have the same y coordinate as the point (2, 2) and it would also have the same x coordinate as (-5, -4).
Hence the fourth coordinate is (-5, 2)
