Answer:
4
Step-by-step explanation:
Please write 0,0 and 4,16. as points: (0, 0) and (4, 16). As we go from the first to the second point, x increases by 4 and y by 16. Thus, the slope of the line through these two points is
m = rise/run = 16/4 = 4.
This is the same result as
16 - 0
m = ------------ = 4
4 - 0
