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.

The first line has a slope of 1/3 and intercept of 4 and the second line has a slope of 2 and intercept of -1

Equation of a line graph

The standard equation of a line is expressed as Ax + By. = C

Given the following equations

x − 3y = −12

2x − y = 1

Write in slope-intercept form to have:

-3y = -x - 12

y = 1/3x + 4

The first line has a slope of 1/3 and intercept of 4

For the equation 2x - y = 1

y =2x - 1

The second line has a slope of 2 and intercept of -1
