There are the same signs so you'd just add them together and use whatever sign they are..
Given:
Cheshire Road Shelby Road
Plot 1 40 yards 48 yards
Plot 3 x 56 yards
To solve for x, we get the ratio and proportion of both plots.
40/48 = x/56
Do cross multiplication.
40 * 56 = 48 * x
2,240 = 48x
2,240/48 = 48x/48
46.67 = x
Plot 3 of Chesire Road measures 46.67 or 46 2/3 yards. Choice A.
The slope can be calculated with the following formula:

In this case, you have the following points:
