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 2

Write the above equation in the form y = mx + c, then c will be the y-intercept.

Write the above equation in the form x = my + b, then b will be the x-intercept.

Answer 3

write the equation in the form x/a+y/b=1 by dividing both sides by -21 from there a is the x-intercept and b is the y-intercept @kaylamarie081
