Question

Find the slope of the two points? (3, -8) (-7, -3)

Answer 1

`-1/2`

Explanation:

To find the slope, or gradient, you use the formula:
change in `y` `-:`change in `x`

The change in `y` is the second `y` coordinate take away the first `y` coordinate. Therefore it is `(-3) - (-8) = 5`

Do the same for the change in `x`:
`(-7) - 3 = -10`

Therefore the gradient would be:
`5 -: (-10) = -1/2`

Answer 2

`-1/2`

Explanation:

The slope of line passing through `A(x_1.y_1)and B(x_2,y_2)` is
`m=(y_2-y_1)/(x_2-x_1)`.
Here,`A(3,-8)andB(-7,-3).`
`:.m=(-3-(-8))/(-7-(3))=(-3+8)/(-10)=5/(-10)=-1/2`
