Graph x = 3 and 3x - 4y = 12 on a rectangular coordinate system This question is from textbook An Incremental Development

Answer by praseenakos@yahoo.com(507) (Show Source): You can put this solution on YOUR website!

3x - 4y = 12
First of all rewrite the equation in terms of x.
that is, y = 3x/4 - 3
Now give arbitrary values to x and get corresponding values of y.

Using these points, plot the graph.

The graph x= 3 is a straight line which passes through 3 on x axis and is parellel to the y axis.You can draw it in the resulting graph)If you cannot draw, please submit the question again.

Then the solution is the [point of intersection of these two graphs.
That is ( 3 , -1)
