Answer:
Altitude: y=(-6/22)x
Median :y=(1/2)x+1
Explanation:
First the line that passes through (-4,-2) and (18,-8) slope=
(y2-y1)/(x2-x1)slope=
(-8-(-2))/(18-(-4))=
(-8+2)/(18+4)=-6/22
perpendicular lines have slopes the multipy to
-1-6/22
times
-1 times both sides by
-22/6=22/6
that is the slope of the line that is the altitude have to use point slope from the equation of a line that passes through
(x1,y1) and has slope of m - y1=
m(x-x1) so that passes through B (4,4) and has slope of
22/6y-4=22/6(x-4)y-4=22/6x-44/3y=(22/6)x-32/3
