Answer:

y - 8 = 4(x - 2)

Step-by-step explanation:

Note that as we increase any x value by 1, the corresponding y value increases by 4.  Thus, the slope is 4.

Using the slope-intercept formula, we get:

y - 8 = 4(x - 2)

Check:  If x = 5, does this formula result in y = 20?

y = 8 + 4(x - 2) with x = 5 comes out to y = 8 + 4(3)  =  8 + 12 = 20.  YES
