Answer:
A
Explanation:
Givens
y2 = 15
y1 = 0
x2 = 3
x1 = 0
Equation
slope = (y2 - y1) / (x2 - x1)
Solution
The question is a bit unfair. It looks like you should be answering one. It's not true. What makes it not so is that the axis (x and y) have different intervals.
Substitute the givens into the equation
slope = (15 - 0) / (3 - 0)
slope = 15 / 3
slope = 5
Answer Slope = 5 or A
