Question

What is the equation of the line with slope `m= -11` that passes through `(7,13)`?

Answer 1

`11x+y=90`

Explanation:

Using a "slope-point" form:
`color(white)("XXX")(y-13)/(x-7)=-11`
which is a valid answer, but normally we would rearrange this as:

`color(white)("XXX")y-13=-11x+77`

`color(white)("XXX")11x+y=90` (which is in "standard form")
