Question

Two lines, A and B, are represented by equations given below:

Line A: y = x – 4
Line B: y = 3x + 4

Which of the following shows the solution to the system of equations and explains why?


A. (–3, –5), because the point satisfies one of the equations
B. (–3, –5), because the point lies between the two axes
C. (–4, –8), because the point satisfies both equations
D. (–4, –8), because the point does not lie on any axis

Answer 1

what do you think?

Answer 2

B

Answer 3

not B

Answer 4

then i don't know!

Answer 5

can you help

Answer 6

sub the first equation into the the second

Answer 7

\(x - 4 = 3x + 4\)

do you know how to solve for x?

Answer 8

plug in the given values to see which ones fit

Answer 9

i tried c that might work

Answer 10

is it right?

Answer 11

you got the ordered pair (-4,-8)

Answer 12

I would say D because the point isn't on the x or y axis

Answer 13

thank you veru much mehek

Answer 14

your welcome
