What is the equation of a line through (0, 3) with slope 4?
A.
y = 4x - 3
B.
y = -4x + 3
C.✓ Correct
y = 4x + 3
D.
y = 3x + 4
Detailed Explanation
Choice C is the best answer. y = mx + b = 4x + 3
Why others are wrong:
A: y = 4x - 3 is incorrect because it does not satisfy the equation.
B: y = -4x + 3 is incorrect because it does not satisfy the equation.
D: y = 3x + 4 is incorrect because it does not satisfy the equation.
