The rate of change between any two points on a straight line can be calculated by finding the slope of the line.
Using the points (0,10) and (5,20), we can find the slope using the formula:
m = (y2 - y1) / (x2 - x1)
m = (20 - 10) / (5 - 0)
m = 10 / 5
m = 2
Therefore, the rate of change is 2.
a graph has the points (0, 10) (5, 20) (10, 30). the graph does not curve or turn anywhere, what is the rate of change
