Question

PLEASE HURRY Aline has a slope of -1/2 and a y-intercept of -2. What is the x-intercept of the line?

Answer 1

x- intercept = - 4

Explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = -
`(1)/(2)` and c = - 2 , then

y = -
`(1)/(2)` x - 2 ← equation of line

To find the x- intercept let y = 0

0 = -
`(1)/(2)` x - 2 ( add 2 to both sides )

2 = -
`(1)/(2)` x ( multiply both sides by - 2 to clear the fraction )

- 4 = x

The x- intercept is - 4
