Help it’s (Graphing Lines in Slope-Intercept Form) 7th grade work

Answers

Answer:

y=mx+b

Step-by-step explanation:

to find the slope, pick two points (easiest if its an even point without decimals). the equation to find slope is m= y2-y1/x2-x1. Once you plug those in, from the two points, you should get a fraction or whole number--depends if it's simplifiable or not. Then plug that in to point slope form: y-y1= m (<the slope) (x-x1). The negatives by y1 and x1 in this equation make the number either negative or positive--if the number is negative it turns positive, and if it's positive it turns negative. Once you plug in those values, you should distribute the slope to the parentheses and combine like terms.

Answer:

Second one : x=-8+1/2

Step-by-step explanation:

-4x+8=42

We move all terms to the left:

-4x+8-(42)=0

We add all the numbers together, and all the variables

-4x-34=0

We move all terms containing x to the left, all other terms to the right

-4x=34

x=34/-4

x=-8+1/2

[16] 1/4’s are in 4.
[5] 1/3’s are in 1 2/3
[3] 1/5’s are in 3/5.

2. 16
This is because if you do keep change flip you will have 4/1*4/1 by keeping the four and just changing it into an improper fraction. Changing the division sign into a multiplication sign and then flipping the 1/4 to 4/1. Than your will simplify 4/1*4/1 is 16/1. Than if you simply 16/1 you will get just 16.
3. 5
This is the same thing but you will make the 1 2/3 into an improper fraction and that is by multiplying the 1 by the denominator (3) and then adding by the numerator. Making you get 5/3 and then using keep change flip you will have 5/3*3/1 making 15/3. Than simplifying into just 5. This is because 15 divided by 3 is equal to three.
4. 3
Same thing just use keep change flip. Than you have 3/5*5/1 and that is equal to 15/5 making it 3.

Hope this can make it easier for you to understand :)
