Question

How do you find the slope of a line passing through the points (2, 9) and (-4, 8)?

Answer 1

`"slope "=1/6`

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)=(2,9)" and "(x_2,y_2)=(-4,8)`

`rArrm=(8-9)/(-4-2)=(-1)/(-6)=1/6`
