Explanation
PROBLEM
Line L1 is y = 3x + 2, L2 is y = 3x - 5. Are they parallel, perpendicular, or neither?
Line L1 is y = 3x + 2, L2 is y = 3x - 5. Are they parallel, perpendicular, or neither?
A.
same line
B.
neither
C.✓ Correct
parallel
D.
perpendicular
Detailed Explanation
Choice C is the best answer. Same slope = 3, so parallel
Why others are wrong:
A: same line is incorrect because it does not satisfy the equation.
B: neither is incorrect because it does not satisfy the equation.
D: perpendicular is incorrect because it does not satisfy the equation.
