Question

What is the slope of the line passing through the following points: `(3,15) ; (-2, -4)`?

Answer 1

`"slope "=19/5`

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)=(3,15)" and "(x_2.y_2)=(-2,-4)`

`rArrm=(-4-15)/(-2-3)=(-19)/(-5)=19/5`
