Set 11: Linear Functions

Explanation

Answer: A

Find the equation of the line parallel to $y = 5x$ passing through $(1, 6)$ .

$y = 5x + 1$

✓ Correct

$y = 5x + 6$

$y = 5x - 1$

$y = \frac{1}{5}x + 6$

Detailed Explanation

Choice A is correct. Choice A is the correct answer. Use point-slope. 1. Slope: 5. 2. Point: $(1, 6)$ . 3. Equation: $y - 6 = 5(x - 1) \rightarrow y = 5 x - 5 + 6 \rightarrow y = 5 x + 1$ . Strategic Tip: Check the point: $6= 5(1) + 1$ . Correct. Choice B is incorrect because intercept error. Choice C is incorrect because it results from an error in the solution process. Choice D is incorrect because slope error.

Key Steps:

•

The correct answer is $y = 5x + 1$

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.
