Question

Which of the following equations
best represents the relationship
between x and y?
A. y=14x-1
B. y=-4x + 2
C. y = 4x + 2
D. y = 4x-1

Answer 1

Answer:

There is a y-intercept at -1, so answer choices B and C are incorrect. There is another point at (1, 3). Using the slope formula, we find that the rate of change is 4, so the correct answer is D.
