Question

What is the slope of the line passing through the following points: `(-1,3) ,(-3, -6)`?

Answer 1

First of all you need the formula of the slope which is
`(y_2-y_1)/(x_2-x_1)`
Then use these values and place them in their designated places
`y_2= -6`
`y_1=3`
`x_2=-3`
`x_1=-1`
so: `(-6-3)/(-3-(-1))`

`(-9)/(-3+1)` Remember `(-)*(-)` is `(+)`

`(-9)/(-2)`

so gradient is `4.5`
remember to cancel out the `-` sign
