:
Put it in the "y =" form
:
3x + 2y = 6;
:
2y = 6 - 3x; subtracted 3x from both sides
:
y = 6/2 - (3/2)x; divided both sides by 2
:
y = 3 - 1.5x
:
Make a table to plot x & y
Subsitute ea value for x in the equation to find y:
An example for the 1st values, when x = -2:
y = 3 - 1.5x
y = 3 - 1.5(-2)
y = 3 - (-3)
y = 3 + 3
y = 6
:
x | y
-----
-2| 6
-1| 4.5
0 | 3
+1|1.5
+2| 0
+3|-1.5
+4|-3
You get the idea
:
Your graph should look like this:

Life is too short to panic over math.
graph 3x+2y=6
:
This is the intercept method.
Let x=0 and solve for y. This is your y-intercept where the line crosses the y-axis.
3(0)+2y=6
0+2y=6
2y/2=6/2
y=3
Plot (0,3)
:
Now let y=0 and solve for x. This is your x-intercept where the line crosses the x-axis.
3x+2(0)=6
3x+0=6
3x=6
3x/3=6/3
x=2
Plot (2,0)
Connect the points and you have a line that looks like this:
Happy Calculating!!! Remember, math is your friend!!!
