# What is the slope of the line between  (7,18)  and  (11,2 ) ?

Feb 6, 2016

slope $= - 4$

#### Explanation:

The points are :
(7,18) = color(blue)(x_1,y_1
(11,2) = color(blue)(x_2,y_2

The slope is found using formula
slope =(y_2-y_1)/(x_2-x_1

=(2-18)/(11-7

=(-16)/(4

$= - 4$

The slope of a line is rise/run.

#### Explanation:

In other words, it is the change in y over the change in x.

Hence, $\frac{2 - 18}{11 - 7}$

The answer is $- 4$

The slope of the line is $- 4$
