Im not explaining for each cause that would take too long, just know you plug in the y and x into the formula y1-y2/x1-x2. So for the first one, you would have -1--1 / 4--2 but when there are two subtractions signs it turns into a plus so -1+1 / 4+2
ANSWER
x=12, y=10
EXPLANATION
The diagonals of a parallelogram bisect each other.
This implies that;
AE=EC
Also, DE=EB;
Put equation (2) in (1).
Expand;
Put x=2, into equation (2).
D

*The underlined problems is what you do first*
True
3k-14=3(k-5)+1
3k-14=3k-15+1
3k-3k=14-15+1
0=14-15+1
-14=-15+1
-14=-14
