we are given two points
(x1,y1)=(0,3)
(x2,y2)=(8,7)
so, we get


(a)
we know that slope of parallel lines are always equal
so, we can use formula

now, we can plug values


............Answer
(b)
we know that slope of perpendicular line is -1/m
so,

now, we can plug value

AC + CE = AE so AC = AE - CE
AC = (x+50) - (x+32)
AC = x+50-x-32
AC = 18
