Draw a line representing the “rise” and a line representing the “run” of the line. State the slope of the line in simplest form.
Oksanka [162]

The slope of the line in its simplest form is 3.

The slope of a line is Slope=\frac{Rise}{Run}.

We need to find the slope of the line in its simplest form.

<h3>What is the slope?</h3>

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope is often denoted by the letter m; there is no clear answer to the question of why the letter m is used for slope.

Select any two points on the line like A and B.

From the below figure it is clear that

Rise = Change in y = -2-(-5) = 3

Run = Change in x = 9-0 = 9

Now, \frac{9}{3} =3

Therefore, the slope of the line in simplest form is 3.
