Question

How do you find the slope of the line through the following pairs of points (3, -7) and (12, -7)?

Answer 1

`"slope "=0`

Explanation:

`"calculate the slope m using the "color(blue)"gradient formula"`

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

`"let "(x_1,y_1)=(3,-7)" and "(x_2,y_2)=(12,-7)`

`m=(-7-(-7))/(12-3)=0/9=0`
