Answer:

y = 4x - 8

Explanation:

To write the equation of a line include a slope and y intercept

y = mx + b

To find the slope use the formula y2 - y1/ x2 - x1

First find 2 points of the line then plug it into the formula

(2, 0) & (6, 16)

16 - 0/6 - 2 (4)

Now it is y = 4x + b

To find b plug in a point and solve for b

0 = 4(2) + b

b = -8

y = 4x - 8
