Graph Y equals x plus 4?

Answer 1

An easy way of solving this equation involves the use of a table. List several arbitrary x values on the left side and then their respective y values in the right side of the table:

X Y

0 4

1 5

2 6

3 7

4 8

5 9

With the x and y values shown on the above chart, plot these values on a graph and it will depict a diagonal line intersecting the y-axis at 4 and intersecting the x-axis at -4.
