Question

line segment RS is perpendicular to line segment PQ, and the coordinates are R(4,-5) S(-8,4) P(0,6) and Q(-3,y) what is the value of y ?

Answer 1

Use slope1 * slope2 = -1 .... for 2 perpendiucular lines

here slope of RS = (-5 - 4)/(4-(-8)) = - 9/12 = - 3/4
slope of PQ = (6 - y)/(0+3) = (6-y)/3
multiply the two to get
(y-6)/4 = -1

y =2
