Question

Y=?

Answer 1

Hi Ciera,

Recall that the slope-intercept form equation is y = mx + b.

We need to figure what the slope, m, and the y-intercept, b, is.

To find the slope, we use the rise over run equation:

m = y2 - y1 / x2 - x1

m = 6 - 4 / 3 - 2

m = 2

Now we plug in value for m and one our given coordinates (either one will work) to find the y-intercept, b:

4 = (2)(2) + b

b = 0

Therefore, our equation is: y = 2x + 0 --> y = 2x
