Question

Find the slope of the line passing through the points (1, -1) and (4, -2).

Answer 1

`slope=-(1)/(3)`

Explanation:

To find the slope of the two points (1, -1) and (4, -2) we have to use the slope formula.

`slope=(y_(2)- y_(1) )/(x_(2) -x_(1) )`
`slope=((-2)- (-1))/(4 -1)`

`slope=(-1 )/(3)=-(1)/(3)` can also be written as a decimal
`slope=-0.333333`
