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.
Yes! Just like if I told you three shapes, and that one and two are circles, and then I told you the third was the same as the second, they would all be circles!
