Answer:
(- 10.5, 0 ) and )0, - 21 )
Step-by-step 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 )
