Answer 1

Answer:

Answer:

The y-intercept is -21. The x-intercept is -10.5 or $-\frac{21}{2}$.

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

Step-by-step explanation:

To find the y-intercept, you would plug in 0 for x.

y = -2x - 21

y = -2(0) - 21

y = 0 - 21

y = -21

The y-intercept is -21.

To find the x-intercept, you would plug in 0 for y.

y = -2x - 21

0 = -2x - 21

2x = -21

x = -21/2

x = -10.5 or $-\frac{21}{2}$

The x-intercept is -10.5 or $-\frac{21}{2}$.
