You can put this solution on YOUR website! write a equation that is perpendicular to y=5x+7 and passes through (-15, 6)
...
compare with y = mx +b
m= slope = 5
slope of line perpendicular to this line will be -1/5.
..
point (-15,6)
plug value of x,y &m to find b
6=-1/5 * -15 +b
6=-3+b
b=9
y=-x/5 +9 is the equation
