Ok so do you know how to do slope
OpenStudy (anonymous):
not really
OpenStudy (perl):
$$
\Large slope~m = \frac{y_2-y_1}{x_2-x_1}
$$

so In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. Slope is often denoted by the letter m. The direction of a line is either increasing, decreasing, horizontal or vertical. A line is increasing if it goes up from left to right.
