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

What defines an x-intercept?

Answer 2

find the point of intersection
if x=0 then y = -3
if y=0 then x= -21

Answer 3

then u'll be getting two pts of the line
