Your graph will be a straight line. You can set values for xx and evaluate the correspondent yy to find the point(s) used to plot your line.

Explanation:

This equation corresponds graphically to a straight line.
The line is inclined downwards and this can be seen by its slope -3−3 which is the coefficient of xx. This negative slope tells you that every time xx increases of 11 unit then yy decreases of 33.

The line also cross the yy axis at 44.

We can plot the line with two points only that can be found as:
set x=0x=0 then y=4y=4 the y-intercept;
set x=1x=1 then y=-3+4=1y=−3+4=1
So you get:
