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

for x intercept put y=0
so x=-21 x intercept (-21,0)
y intercept
put x=0
y=-3
(0,-3)

Answer 2
