Question

How do you find the slope of the line passing through the points (1,1) and (-4,-4)?

Answer 1

`"slope "=1`

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)=(1,1)" and "(x_2,y_2)=(-4,-4)`

`rArrm=(-4-1)/(-4-1)=(-5)/(-5)=1`
