Answer:
4x - 2y = -8--------equation 1
y = 2x + 4
or, -2x+y=4---------equation 2
multiply equation 2 by 2 and solving equation 1and2 we get,
4x - 2y = -8
-4x+2y=8
---------------=
impossible
Answer:
No

Answer:
2. for the first equation, it works, for the second it doesnt so the answer is no
i cant graph for you, but its easy, just use y=mx+b m being the slope which is rise over run
8. x=6, y=-1
10. x=-5 y=5
this is all i could do in such a short notice, but i hope it helped you!
Step-by-step explanation:
for 8, 
for 10,
Answer:
NonLinear line
Step-by-step explanation:
Linearity is the property of a mathematical relationship that can be graphically represented as a straight line. Linearity is closely related to proportionality. Examples in physics include the linear relationship of voltage and current in an electrical conductor, and the relationship of mass and weight.
X by itself is 1, otherwise it is the number to the left
