Question

What is the equation of the line with slope `m= -1` that passes through `(7,4)`?

Answer 1

`x+y-11=0`

Explanation:

The equation of the line passes through `(x_1,y_1) and` has a slope `m` is,
`color(red)(y-y_1=m(x-x_1)rArry-4=-1(x-7))`
we have, `(x_1,y_1)=(7,4)andm=-1`
`y-4=-x+7rArrx+y-11=0`
