You can put this solution on YOUR website!
The equation is given as point-slope form. The included point is (2,-3) and the slope is 2. Slope means vertical change divided by horizontal change. Plot the point and find other points using the slope, and draw the line through the points.

+y+%2B+3+=+2%2A%28+x-2+%29+
Whatever you do to one side of
the equation, you have to do to the
other side also
------------------
The goal is to get the +y+ on
the left side alone
------------------
Subtract +3+ from both sides
+y+=+2%2A%28+x-2+%29+-+3+
-------------------
Now simplify the right side
+y+=+2x+-+4+-+3+
+y+=+2x+-+7+
This is now in the form called
" slope-intercept form " which
makes it easier to plot
------------------------
The slope is +2+ and the y-intercept is +-7+
Here's the plot:
+graph%28+400%2C+400%2C+-10%2C+10%2C+-10%2C+10%2C+2x+-+7+%29+
The slope is how steep the line is and the
y-intercept is where it crosses the y-axis
-----------
Hope this helps
