Question 832663
<pre>
Hi, there--

THE PROBLEM:
Graph the equation 
{{{y + 3 = (1/2) (x - 3)}}}

A SOLUTION:
This is a linear equation, so the graph is a line.

Make a table of several easy points on the line.
If x = 3, then
{{{y+3=(1/2)((3)-3)}}}
{{{y+3=(1/2)(0)}}}
{{{y+3=0}}}
{{{y=-3}}}
The point (3,-3) is on the line.

If x=5, then
{{{y+3=(1/2)((5)-3)}}}
{{{y+3=(1/2)(2)}}}
{{{y+3=1}}}
{{{y=-2}}}
The point (5,-2) is on the line. 

If x = -1, then
{{{y+3=(1/2)((-1)-3)}}}
{{{y+3=(1/2)(-4)}}}
{{{y+3=-2}}}
{{{y=-5}}}
The point (-1,-5) is on the line.

Now plot these three points on the x-y axes. They should line up so you can draw a line through them.

{{{
graph (350,350, -8, 8, -8, 8, 0.5x - 4.5)
 }}}







Hope this helps! Feel free to email if you have any questions about the solution.

Good luck with your math,
