Now that I have the slope there are two expressions I could use to find the equation of the line
To use the first form, the point slope form, I would choose one of the two points A or B and substitute its coordinates for x_{1} and y_{1}. To use the second form, the slope intercept for, choose one of the points A or B, substitute its coordinates for x and y and then solve for b. I'm going to use the point slope form and use the point B. Thus I get
The standard form of a line is
so I need to manipulate (y  6) = 2 (x  7) into this form. Multiplying the 2 through the parentheses on the right I get
Finally add 6 to each side and subtract 2x from each side to get
Now try this with the points you were given,
