Question

What graph goes with these following equations?


A)2x – 2y = 8
4x + 4y = 16

B)2x – 2y = 8
4x – 4y = 16

C)2x + 2y = 8
4x + 4y = 16

D)2x + 2y = 8
4x – 4y = 16

Answer 1

here is the graph

Answer 2

There's no intersection

Answer 3

Hmmm

Answer 4

That's because it's the same graph. Now we just have to figure out which one is right. in this case we have to use the x and y intercepts to figure this out

Answer 5

c..

Answer 6

x/4=y/4=1
this show that in both axis the cutten part is 4,0 and 0,4

Answer 7

so its B? are you sure?

Answer 8

Yeah, I realize that for c, the slope is negative so it's c

Answer 9

C)
The equation for the line on the plot is x + y = 4
All of the other alternatives offered have sign problems.
