Use an equation to find the value of k so that the line passing through (−2,k) and (2,0) has a slope of −1.

k = 4

Step-by-step explanation:

Calculate the slope m using the slope formula, then equate to - 1

m =

with (x₁, y₁ ) = (- 2, k ) and (x₂, y₂ ) = (2, 0 )

m = = = , then

= - 1 ( multiply both sides by 4 )

- k = - 4 ( multiply both sides by - 1 )

k = 4

step-by-step explanation:

we have

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
