Answer 1
Answer: If we use similar triangles ( as shown in the attachment ) we will see that the line CM is also  1/4 *( yC-yD)= 1/4*(2+2) = 1/4*4 =1
Answer: y-value of that point is A) y=1.
Answer 2
Answer: Hello,

A=middle of [CD] =((1-4)/2,(2-2)/2)=(-3/2,0)
B=middle of [CA]=((1-3/2)/2,(2+0)/2)=(-1/4,1)

|2x + 4| > 14
2x+ 4 = 14  2x + 4 = -14
x = 5 or x = - 9
2*5 = 10 +4 = 14 Yes
2*-9 = -18 + 4 = - 14 Yes
2x > 10  2x < - 18
X > 5
X < -9
