Answer:
2x + 4y = 4
-8x + 8y = -16.
Step-by-step explanation:
We can find an equivalent system by multiply the 2 equations by 2.
x + 2y = 2 multiplied by 2 is 2x + 4y = 4.

Answer:
16 Unit
Step-by-step explanation:
With P(-2,1) , Q(6,1) , R(4,-3) , S(4,1) , the triangle and its altitude look like the one attached in figure.
The length of base PQ is the difference in the x-coordinates of P and Q,
6-(-2)=6+2=8 , because the y-coordinates are both the same as 1.
The height (the length of altitude RS is the difference in the y-coordinates of R and S,
1-(-3)=1+3=4 , because the y-coordinates are both the same as 4 .
The area is
.
