Answer:
x-intercept = -6
<h2>y-intercept = -21</h2>
Step-by-step explanation:
x - intercept is for y = 0
y - intercept is for x = 0.
We have y = -2x - 21.
Substitute:
x = 0 → y = -2(0) - 12 = 0 - 12 = -12
y = 0 → 0 = -2x - 12 <em>add 2x to both sides</em>
2x = -12 <em>divide both sides by 2</em>
x = -6
