Which equation is the equation of a line that passes through (-10,3) and is perpendicular to y=5x-7?

Question

1- y=5x+53
2- y=-1/5x -7
3- y= -1/5x +1
4- y= 1/5x +5

Answer 1

you want slope = -1/5

So, the point-slope form of the line is

y-3 = -1/5 (x+10)

Now massage that into one of the choices.
