Answer:
150
Step-by-step explanation:
To find the rate of change between two points, we can use the formula:
Rate of change = (change in y) / (change in x)
Given the points (1,100) and (3,400), the change in y is 400 - 100 = 300 and the change in x is 3 - 1 = 2.
Therefore, the rate of change is:
Rate of change = 300 / 2 = 150
So, the rate of change between the points (1,100) and (3,400) is 150.
