First rearrange the equation by solving for y:
3x-2y%2B5+=+0 Add 2y to both sides.
3x%2B5+=+2y Now divide through by 2 to get y by itself.
%283%2F2%29x%2B5%2F2+=+y or y+=+%283%2F2%29x%2B5%2F2
Now you can graph this by first letting x = 0 and solving for y, then letting y = 0 and solving for x so that you will get two ordered pairs (points) which you can then plot on you coordinate graph paper. Join these two points with a straight line and you will have the graph of the given equation:
y+=+%283%2F2%29x%2B5%2F2 substitute x = 0.
y+=+%283%2F2%29%280%29%2B5%2F2
y+=+5%2F2 The first point is (0, 5%2F2)
y+=+%283%2F2%29x%2B5%2F2 Substitute y = 0.
0+=+%283%2F2x%29%2B5%2F2 Subtract 5%2F2 from both sides.
-5%2F2+=+%283%2F2%29x Multiply both sides by 2%2F3.
-5%2F3+=+x The second point is (-5%2F3,0)
The graph looks like this:
graph%28400%2C400%2C-5%2C5%2C-5%2C5%2C%283%2F2%29x%2B5%2F2%29
For displaying the graph on your calculator, assuming that you have a graphing calculator such as TI-83, TI-86, etc press the "graph" key then, for y%5B1%5D enter highlight%28%283%2F2%29x%2B5%2F2%29 followed by the "enter" or "=" key.
