Mark the point

Calculate the coordinates of a second point on the line. The slope is

which is the same as

, so the change in the vertical direction is

and the change in the horizontal is

.

New

-coordinate (horizontal):

New

-coordinate (vertical):

So a new point on the line is

Plot the new point. Draw a straight line through the two points.

Note: You could also have written the slope as

and then added a negative 1 to the

-coordinate and added 1 to the

-coordinate. In fact, you could have chosen any number you like, say

and added its negative to the

-coordinate and its positive to the

-coordinate (or vice versa), and achieved the same results.

My calculator said it, I believe it, that settles it
