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

y=mx+b

y=(x/7)-21

b = -21 which equals y intercept

Answer 2

x intercept..let y = 0 then solve for x

x + 7y = -21
when y = 0
x + 7(0) = -21
solve for x

y intercept...let x = 0 then solve for y

x + 7y = -21
when x = 0
0 + 7y = -21
solve for y

@geo_mitch you forgot something ;)
