Point M is the midpoint of CD. What is the value of a in the figure?
C(a, 2a)
M(6,4)
D(9,2)

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

-12 > a

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
