Convert the equation #3y-2x=6#to 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.
