A linear function has a slope of 4 and a y-intercept of (0,-8). What is the x-intercept of the line?

The answer to your question is 2 or (2, 0)

Step-by-step explanation:

Data

slope = m = 4

y-intercept = - 8

Process

1. - Write the equation of the line in the slope y-intercept

y = mx + b

In this equation:

m = slope

b = y-intercept

-Substitution

y = 4x - 8

2. - To find the x-intercept, consider that y = 0 and solve for x.

0 = 4x - 8

4x = 8

x = 8/4

x = 2 or (2, 0)
