Set 17: Linear Functions

Explanation

Answer: A

Determine if the lines y=3x2y = 3x - 2 and y=3x+5y = 3x + 5 are parallel, perpendicular, or neither.

A.

Parallel

✓ Correct
B.

Perpendicular

C.

Neither

D.

Coincident

Detailed Explanation

Choice A is correct. Choice A is the correct answer. Compare slopes. 1. Line 1: m=3m = 3. 2. Line 2: m=3m = 3. 3. Conclusion: Slopes are equal, intercepts differ. They are parallel. Strategic Tip: Same slope = Parallel. Choice B is incorrect because slopes are not negative reciprocals. Choice C is incorrect. Choice D is incorrect because intercepts differ.

Key Steps:

The correct answer is Parallel

Why others are wrong:
B: Choice B is incorrect and may result from a calculation error.
C: Choice C is incorrect and may result from a calculation error.
D: Choice D is incorrect and may result from a calculation error.
