Answer:
Step-by-step explanation:
Given system:
- x + 4y = -8
- -1/4x + y = -1
1. Multiply the second equation by - 4 to get:
- (- 4)(-1/4x + y ) = (- 4)(- 1)
- x - 4y = 4
2. Now, add this up with the first equation:
- x + 4y + x - 4y = - 8 + 4
- 2x = - 4
- x = - 2
3. Find the value of y:
- - 2 + y = - 8
- y = - 8 + 2
- y = - 6
The solution is (- 2, - 6)

Answer:
Two lines, both in the same plane, that never intersect are called parallel lines. Parallel lines remain the same distance apart at all times. The symbol // is used to denote parallel lines.
how to prove that two lines are equal: If two lines are cut by a transversal and the alternate exterior angles are equal, then the two lines are parallel. Angles can be equal or congruent; you can replace the word "equal" in both theorems with "congruent" without affecting the theorem. So if ∠B and ∠L are equal (or congruent), the lines are parallel. therefore the answer is E. The two lines are everywhere equidistant.
