Question

What is the slope of the line passing through the following points: `(-7,-5); (3,-9)`?

Answer 1

`5y+2x+39=0`

Explanation:

First you have to find the gradient

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

`m=(-5+9)/(-7-3)=4/-10=-2/5`

Using the point gradient method,

`(y+5)=-2/5(x+7)`

`5y+25=-2x-14`
`5y+2x+39=0`
