Write the equation for the vertical line that contains point E(8,6).
y = 6 is my answer

If BCDE is congruent to OPQR, then line segment DE is congruent to __________.
I said line segment QR.

Answer 1

can you draw vertical line ? like in co-ordinate axis.

Answer 2

if you draw, you would see that its distance from y-axis remains constant
distance from y-axis means x co-ordinate.
