You can
put this solution on YOUR website!
You didn't state what you want. Do you want the equation of the line through
P(-2,1) parallel (or maybe perpendicular) to the line y=1/4x-3?
Do you want the distance from the point P(-2,1) to the line y=1/4x-3?
You must tell us what you want us to do. Otherwise, we can't know.
