The answer is the third one
Hope this helps! :)
We can use the points (1, 2) and (3, -4) to solve.
Slope formula: y2-y1/x2-x1
= -4-2/3-1
= -6/2
= -3
Hope This helped! Good Luck!
Answer:
-y^2
Step-by-step explanation:
x(x-2y)-(y-x)^2=
Distribute
x^2 -2xy -(y-x)^2=
Foil
x^2 -2xy -(y^2 -2xy+x^2)=
Distribute the minus sign
x^2 -2xy -y^2 +2xy-x^2=
Combine like terms
-y^2
The Area of a triangle is 1/2 base×height So 8×3/2=12
