Question

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

Answer 1

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

Answer 2

\[y=\frac{ 4 }{ 3 }x-3\]

Answer 3

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.

Answer 4

You are absolutely right!

Answer 5

so follw tkhunny's instructions, plot the points and graph the line.
