Draw the line X+Y=3 on the graph from x = -3 to x = 3
The easiest way is probably to write a table with all of the X and Y values. Write out all of the x values and substitute them into the formula to see what value of Y you need to get the value of 3.X Y-3 6-2 5-1 40 31 22 13 0Now plot these coordinates on the graph and connect the dots in a straight line.
