Question

What is the equation of the line?



A.
7 x − 4 y equals 28

B.
7 x plus 4 y equals 28

C.
negative 4 x plus 7 y equals 28

D.
negative 4 x plus 7 y equals negative 28

Answer 1

Why don't you start out by writing A-D as equations with y isolated?

Answer 2

A.7x-4y=28
B.7x+4y=28
C.-4x+7y=28
D.-4x+7y=-28

Answer 3

you need to run then through i forgot the process to make them look like ex"y=4x+5"

Answer 4

its called slope intercept form

Answer 5

it makes this way easier

Answer 6

bumps but doesn't reply

Answer 7

We know that (0,-4) is a point.
A.7x-4y=28
0+16 doesn't equal 28, so it can't be A
B.7x+4y=28
0-16 doesn't work either

C.-4x+7y=28
D.-4x+7y=-28

Which one, C or D, works?

Answer 8

im not sure which one

Answer 9

Plug in 0 for x and -4 for y.

Answer 10

i think d

Answer 11

no wait its c

Answer 12

It's C
