Which graph shows a function that crosses the x-axis at negative three comma zero and has a rise over run of four-thirds?

Question

anonymous · Answer

y=mx+b
m is your rise over run and b is where you cross your x axis so...
m = 4/3
b = -3

anonymous · Answer

$$y=\frac{ 4 }{ 3 }x-3$$

tkhunny · Answer

The problem statement gives an x-intercept, not a y-intercept.

y = mx + b

We are given the slope, 4/3.

y = (4/3)x + b

We are given a point, (-3,0)

0 = (4/3)(-3) + b

Solve for b.
