Answer:
your answer is A
Step-by-step explanation:
just did the test
The diagonals of a rectangle are congruent so set them equal to each other to get x = 2x - 7. isolate the variable (0 = x - 7 — x = 7) to get x = 7. the diagonals are seven.

(c) 
So 
(d) 
Answer:
B. -y = -x
Step-by-step explanation:
When the values on both sides of the equal sign are changed, it becomes a negative number.
We have the slope m = (6-3)/(4-1) = 3/3 = 1;
Then, y - 3 = 1·( x - 1);
finally, y = x + 2.
