  1. (3,2)....because when finding the slope, we find the the slope of mn and the slope of op are negative reciprocals.

    2. y = 5x - 7.....slope here is 5....perpendicular line has a negative reciprocal slope...so the slope has to be -1/5

    y= mx + b
    slope(m) = -1/5
    (-10,3)...x = -10 and y = 3
    now we sub and find b, the y int
    3 = -1/5(-10) + b
    3 = 2 + b
    3 - 2= b
    1 = b
    so ur perpendicular equation is : y = -1/5x + 1
