Question

Find the x- and y-intercepts of the graph of the equation.

f(x) = 4x – 12
x-intercept
(x, y) =
y-intercept
(x, y) =

Answer 1

x intercept is (3, 0). y intercept is (0, -12).

Explanation:

x intercept is when y = 0. [f(x) = y] So 0 = 4x - 12. Solving for x gives you a value of 3. [12 = 4x; divide by 4]

y intercept is when x = 0. So y = 4(0) - 12. Solving for y gives you a value of -12. [y= 0 - 12; y = -12]
