Two lines are guaranteed to be coplanar if they: Lie in the same plane. Lie on the same line (are collinear) and Lie in the same plane. ... Collinear points are two or more points that lie on the same ____.
Reflection does not preserve orientation.
Dilation (scaling), rotation and translation (shift) do preserve it.
(3)(-5x+y=-3)
(5)(3x-8y=24)
-15x+3y=-9
15x-40y=120
3y=-9
-40y=120
-37y=111
Divide both sides by -37
y=-3
To solve for x. Choose one equation from the given and plug what you get in Y.
I'll choose, -5x+y=-3
So, -5x+(-3)=-3
-5x=0
Divide both sides by -5
x=0/-5
Hope, this helps.
