Question

Help ASAP pls What is the y intercept of the linear equation shown on the graph

A. (0,-70)
B. (0,-50)
C. (0,1/2)
D. (0,100)

Answer 1

b

Explanation:

trust

Answer 2

(0, -50)

Explanation:

pick any 2 points such as (100,0) and (120,10)

to get from point (100.0) to point (120,10) you had to rise 10 and run 20

so the slope m =rise 10/run20= 1/2

the equation of the line is (y-y1)=m(x-x1)

(y-0)=(1/2)(x-100) for the slope m=1/2 and point on the line (100,0)

y=( x/2)-50 if you distribute

compare this with the equation

y=mx+b wher m=slope and bb is y-intercept

so the y-intercept is -50
