Question

What is the slope intercept form of the line passing through `(-1,-2)` with a slope of `-1`?

Answer 1

`y=-x-3`

Explanation:

Because we're given a slope and a point, we can use the point-gradient formula:
`y-y1=m(x-x1)`

For this question, `m` is `-1` and `(x1,y1)` is `(-1,-2)`. We then put this data into the formula to get:
`y+2=-1(x+1)`
`y+2=-x-1`
`y=-x-3`
