Question

What is the equation of the line passing through `(-1,-1)` and `(1,14)`?

Answer 1

`15x-2y=-13`

Explanation:

Slope=`(y2-y1)/(x2-x1)`
Slope=`(14+1)/(1+1)`
Slope=`15/2`

Equation of line passing through 2 points is `y-y1=m(x-x1)`
where `m` is the slope

So the equation of the line is `y+1=15/2(x+1)`
`2y+2=15x+15`
`15x-2y=-13`
