Question

Choose the system of equations which matches the following graph.
a) 3x + 4y = 24
3x + y = –3

b) 3x + 4y = 24
3x – y = 3

c) 3x – 4y = –24
3x + y = –3

d) 3x – 4y = –24
3x – y = 3

Answer 1

@abb0t hey i see u helping everybody can u help me?

Answer 2

I am not giving answers if that's what you're getting at. I am helping. So, what i AM GOING to suggest is that you rewrite the function(s) in the form of point slope. As you can see \(\sf \color{red}{y=mx+b}\) where m = slope or rise OVER run. and b = y-coordinate (meaning the line shifted b units up or down.

Since the lines are both on Q1 (meaning quadrant 1), that must mean that the \(\sf\color{red}{b}\) must be a positive value.

Answer 3

@abb0t so its not c or d
