To make a linear equation, you have to find the slope and the y intercept.

To start, find the slope.

The value of X decreases by 5 and the value of Y decreases by 6.

This was done by using the slope formula.

Thus the slope is, (dont forget rise over run!)

-

Now we have y = - + b

Use the slope and input one of the coordinates to solve for b (the y-intercept)

Therefor the linear equation for the line is

y =
