Question

What is the equation of the line that goes through `(1,- 19) ,( - 2,- 7)`?

Answer 1

`y+4x+15=0`

Explanation:

`(x1,y1)=(1,-19) & (x2,y2)=(-2,-7)`
Equation format is `(y-y1)/(y2-y1)=(x-x1)/(x2-x1)`
`(y+19)/(-7+19)=(x-1)/(—2-1)`
`-3(y+19)=12(x-1)`
`-3y-57=12x-12`
`3y+12x=-45`
`y+4x+15=0`
