Question

What is the slope of the line passing through `(-4,-8); (-2,-6)`?

Answer 1

`1`

Explanation:

Slope `m` of a line passing through two points `A(x_1,y_1)` and `B(x_2,y_2)` is given by

`m=(y_2-y_1)/(x_2-x_1)`

Here let `A=(-4,-8) and B=(-2,-6)`

`implies m=(-6-(-8))/(-2-(-4))=(-6+8)/(-2+4)=2/2=1`

`implies` slope of the line passing through the given points is `1`.
