Choose the graph that matches the following system of equations: x − 3y = −12 2x − y = 1
picture of coordinate plane with line y equals negative one third x minus 4 and line y equals 2x plus 1. they intersect at negative 2.14, negative 3.29 picture of coordinate plane with line y equals negative x plus 4 and line y equals 2x minus 1. they intersect at 1.67, 2.33 picture of coordinate plane with line y equals one third x minus 12 and line y equals negative 2x minus 1. they intersect at 4.71, negative 10.43 picture of coordinate plane with line y equals 1 third x plus 4 and line y equals 2x minus 1. they intersect at 3, 5

Let's rewrite these equations in y=... form.

x-3y=-12
-3y=-12-x
y=4+1/3x
y=1/3x+4

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

If you equal them to eachother (which eliminates the y) you get:

1/3x+4 = 2x-1
5 = 5/3 x
x = 3
and y=5, so intersection at (3,5)

This answer is the last one of the textual answers in the question.
