Set 1: Linear Functions (Intermediate)

**Choice A is the best answer.** y = mx + b where m = 2, b = 3

Explanation

Answer: A

PROBLEM

What is the equation of a line with slope 2 and y-intercept 3?

y = 2x + 3

✓ Correct

y = 2x - 3

y = 3x + 2

y = -2x + 3

Detailed Explanation

Choice A is the best answer. y = mx + b where m = 2, b = 3

Why others are wrong:

B: y = 2x - 3 is incorrect because it does not satisfy the equation.

C: y = 3x + 2 is incorrect because it does not satisfy the equation.

D: y = -2x + 3 is incorrect because it does not satisfy the equation.
