To check if this point lies on the line, plug in a 2 for x and a y for 1 and solve
x+2y=5
2+2(1)=5
4=5
Since this statement isn't true, then the point doesn't lie on the line
Hope this helps
Its the first one, because x wont be affected, and 1 and -3 is a constant.
-2 + 4i + 1 - 7i + 8 - 5i
7 - 8i
Answer:
65 is the answer.. I used a average calculator https://www.omnicalculator.com/math/average
X-4y=0
