Question

Identify the correct x intercept and y intercept of the equation x + 7y = -21

Answer 1

To find the y intercept, substitute 0 for x. Therefore:
0+7y=-21
y=-21/7
y-intercept = -3

To find the x-intercept, substiture 0 for y. Therefore:
x+7(0)=-21
x=-21

Answer 2

X-Int: -21
Y-Int: -3

Answer 3

so could it be written like this: x intercept = (-3, 0); y intercept = (0, -21)

Answer 4

Yes!
