Question

Use the graph to find the slope (m) and y-intercept (b)

Answer 1

Answer:

Slope=4 y-intercept=(0,-21) or -21

Step-by-step explanation:

To find slope

m=-13-(-17)/2-1

m=4/1

m=4

To find y-intercept

y-(-17)=4(x-1)

y+17=4(x-1)

y+17=4x-4

Subtract both sides by 17

y=4x-21

y-intercept=-21
