Question

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

x intercept = (3, 0); y intercept = (0, 21)

x intercept = (-3, 0); y intercept = (0, -21)

x intercept = (21, 0); y intercept = (0, 3)

x intercept = (-21, 0); y intercept = (0, -3)

Answer 1

help

Answer 2

sub x=0 and find y
sub y=0 and find x

Answer 3

...

Answer 4

Just set up the equation to where it's going to be 0 + 7y = -21 to solve for y, and x + 7(0) = -21 to solve for x.
