Question

What is the x and y intercept of y= -2x - 21 ?

Answer 1

y int = (0, -21)

x int = (-10.5, 0)

solve for them

Answer 2

To find the x-intercept, we need to set y to zero and solve for x:

0 = -2x - 21

2x = -21

x = -10.5

So the x-intercept is -10.5.

To find the y-intercept, we need to set x to zero and solve for y:

y = -2(0) - 21

y = -21

So the y-intercept is -21.

Therefore, the x-intercept is -10.5 and the y-intercept is -21.
