# What is the slope of the line passing through the following points: #(-7,11), (9, -10) #?

##### 2 Answers

#### Explanation:

#"to calculate the slope m use the "color(blue)"gradient formula"#

#•color(white)(x)m=(y_2-y_1)/(x_2-x_1)#

#"let "(x_1,y_1)=(-7,11)" and "(x_2,y_2)=(9,-10)#

#rArrm=(-10-11)/(9-(-7))=(-21)/16=-21/16#

#### Explanation:

First we find

Where

Now we just plug it in, giving us

Now that we have

The line formula is

Now we add

Now we find a common denominator between the constants
