Convert the equation 3y-2x=6to slope-intercept form.

Add 2x to both sides.

3y=2x+6

Divide both sides by 3.

y=2/3x+2

The slope is 2/3 and the y-intercept is 2.

Determine some points on the line by making x=0 and y=0.

If x=0:
y=2/3*0+2
y=2
Point = (0,2)

If y=0:
0=2/3x+2
-2/3x=2
Multiply times both sides by 3.
-2x=6
Divide both sides by -2.
x=-3
Point=(-3,0)

graph{y=2/3x+2 [-10, 10, -5, 5]}

3y-2x=6 is a straight line function
so the easiest way to graph it is to establish two points on the line.
In a case like this one the easiest two points to establish are the x and y intercepts.
By inspection
x-intercept occurs at (-3,0)
y-intercept occurs at (0,2)

Make these two points on a graph and draw the straight line that runs through both of them.
