Answer 1

Answer:

Slope = 3/2

Step-by-step explanation:

Slope = rise/over or change in x/change in y

To find the slope, use two points and the slope formula

Slope formula: (y₂ - y₁)/(x₂ - x₁)

Points (any point): (20, 40) & (40, 70)

Step 1. Plug the two points into the formula (where the first point indicates the firsts x and y coordinates and the second point indicates the seconds x and y coordinates)

(70 - 40)/(40 - 20)

Step 2. Subtract

30/20

Step 3. Simplify

3/2

Answer 2

Y= mx+b, y=3/2+10
30/20=3/2
b=10
