Question

What is the equation of the line with slope `m= -3/7` that passes through `(12,-5)`?

Answer 1

`color(white)(x)y=-3/7x-1/7`

Explanation:

`color(white)(x)y=mx+c`

`=>y=color(red)(-3/7)xxx+c`

For `x=12` and `y=-5`,
`color(white)(x)-5=(-3/7)xx12+c`
`=>-5=-(3xx12)/7+c`
`=>c=5-(3xx12)/7`
`=>c=-1/7`

Quation is:
`=>y=-3/7x-1/7`
