Answer:

(- 10.5, 0 ) and )0, - 21 )

Explanation:

to find the x- intercept let y = 0 in the equation and solve for x

0 = - 2x - 21 ( add 21 to both sides )

21 = - 2x ( divide both sides by - 2 )

- 10.5 = x

then x- intercept = (- 10.5, 0 )

to find the y- intercept let x = 0 in the equation and solve for y

y = - 2(0) - 21 = 0 - 21 = - 21

y- intercept = (0, - 21 )
