Question

How do you find the slope of the line that passes through (-12,15), (18, -13)?

Answer 1

`"slope "=-14/15`

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)=(-12,15)" and "(x_2,y_2)=(18,-13)`

`rArrm=(-13-15)/(18-(-12))=(-28)/30=-14/15`
