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 y intercept make x =0

0 + 7y = -21

solve. ( 0, ? )

for x intercept make y =0.

x + 7(0)= -21

solve.( ? , 0 )

Answer 2

-21/

Answer 3

what is -21 ?

Answer 4

give me the co-ordinates. (x , y)

Answer 5

is x and y is 7?

Answer 6

No solve y = -21/7.... what is y? keep working @primeralph will help you right its bed time.

Answer 7

-3?

Answer 8

@mebs You taunting me?

Answer 9

i think the right answer is b

Answer 10

At x = 0, y = -3 , (0,-3)
at y = 0, x = -21, (-21,0)

Answer 11

D.

Answer 12

ugh. thxs!

Answer 13

You're welcome.
