whpalmer4 · Answer

Formula for finding the slope of a line when you know two points (x1, y1) and (x2, y2) is 

$$m=\frac{(y_2-y_1)}{(x_2-x_1)}$$

Order of the points doesn't matter, you just have to be consistent.

hba · Answer

Use the formula,

$$\huge\ m=\frac{ y_2-y_1 }{ x_2-x_1 }$$

whpalmer4 · Answer

If you end up dividing by 0, the slope is undefined.
