perpendicular: negative reciprocal of 4x: -1/4 find b in  y=mx+b by plugging in the point (-8,-7) -7=-1/4(-8) + b

perpendicular line has the negative reciprocal of slope of the line given. So slope for the equation is m=-1/4 You use the point-slope form{y-y1=m(x-x1)} to find the equation with the piont (-8,-7). I found the equation is y=-1/4x-9.
