We've got 2 points:

(16, -2) and (-12, -9)

Calculate the slope (m) of this line using:

m = (y2 - y1)/(x2 - x1)

m = (-9 - -2)/(-12 - 16)

m = -7/-28

m = 1/4

The line equation is denoted as:

y = mx + b

Let's use the first point (x, y) = (16, -2)

-2 = 1/4(16) + b

-2 = 4 + b

Subtract 4 from each side, and we get:

b = -6

So our equation of the line is:

y = 1/4x - 6

The questions asks for f(0):

y = 1/4(0) - 6

y = 0 - 6

**y = -6**
