Answer: Function A; 14 meters per second
Step-by-step explanation:
For function A, we choose two points to find the slope, which is the speed.
10, 140 and 20,280
slope = m = speed = y2-y1 / x2-x1
= (280 - 140) / (20-10)
= 140 / 10
= 14
The slope of function b is 13, because y=mx+b, where m is the slope.
14>13
so function a> function b
