Question

What is the slope of the line passing through the following points: `(4,9), (1,6)`?

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)=(4,9)" and "(x_2,y_2)=(1,6)`

`rArrm=(6-9)/(1-4)=(-3)/(-3)=1`
