Question

How do you write the equation of the line with slope of -5 and passes through the point (2, -4)?

Answer 1

`y=-5x+6`

Explanation:

`y=mx+c` (where m: gradient of line; c: constant)

Now that we have known variables and gradient, we can find `c`:
`-4=-5*(2)+c`
`c=-4+10=6`

Hence, the equation of this line is:
`y=-5x+6`
