Use elimination to solve the system of equations
2 answers:
Solution:
There are Infinitely many solutions.
Explanation:
We have been given the system of equations
In elimination method, we multiply any of the equation by some constant and then add/subtract the equations to eliminate any variable x or y.
Let us multiply equation 1 by 3
Add equations 3 and 4, we get
We got 0=0, which is always true.
Hence, there are Infinitely many solutions.
C is the correct option.

For this case we observe that the lines AB (red) and CD (purple) are cut at one point.
We observe that the slopes of both lines are different (they are not reciprocal opposites).
Therefore, the lines are not perpendicular.
Answer:
AB and CD are intersecting lines but are not perpendicular.
