Answer 4

am i right with D? or is it C?

Answer 5

It wouldn't be graphs C or D. For both of those graphs, when X=6, Y=0; if you plug those values into the equation, you get 15*6 - 5*0 = 30, which isn't true.

I think you'd want to go with graph A. For that graph, when X=2, Y=0, and when X=0, Y=-6; plug those values into the equation to get 15*2 - 5*0 = 30 and 15*0 - 5*-6 = 30, which are both true; this also works for any other value of X and Y on the line, they will always return the correct result when you plug them into the equation like that.

Another way to solve the problem would be to use algebra to convert the equation into the form y=mx+b, which would make it easy to see what kind of graph you want based on the slope and y-intercept. Either way, I think graph A would be the answer you want

Answer 6

i probably can help

Answer 7

you would want to rearrange your problem

Answer 9

ty i get this now

Answer 10

so -5y+15x=30

Answer 11

divide everything by -5 so that would be
y=-3x-6

Answer 12

divide everything by -5 so that would be
y=-3x-6
