Question

Choose the graph that matches the system of equations(in the comment)?
4x + 2y = –2
x – 3y = 24

Answer 1

First equation:

2y = -2 - 4x
y = -2x -1

So when x = 0, y = -1.
when x = 1, y = -3

Second equation:

x - 3y = 24
-3y = 24 - x
3y = x - 24
y = 3/x - 8

So when x = 0, y = -8
when x = 3, y = -7

Answer 2

Looking at your graphs, that would be c.

Answer 3

Basically when you're trying to analyze lines in a plane, you need to find two points that the line cross.
