Set 1: Linear Functions

Explanation

Answer: A

Which linear function has the largest y-intercept?

$y = -5x + 10$

✓ Correct

$y = 2x + 8$

$2y = 4x + 12$

A line passing through $(0, 5)$ and $(1, 6)$

Detailed Explanation

Choice A is correct. Choice A is the correct answer. Identify intercepts. 1. A: $b = 10$ . 2. B: $b = 8$ . 3. C: Divide by 2 $\rightarrow y = 2 x + 6$ . $b = 6$ . 4. D: Passes through $(0, 5)$ , so $b = 5$ . 5. Max: 10 is the largest. Strategic Tip: Convert all to $y=mx+b$ form first. Choice B is incorrect. Choice C is incorrect. Choice D is incorrect.

Key Steps:

•

The correct answer is $y = -5x + 10$

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.
