To find the rate of change (slope) of the linear function, we can use the formula:
m = (y2 - y1) / (x2 - x1)
Using the values from the table:
m = (3 - (-6)) / (3.2 - 2.6)
m = (3 + 6) / 0.6
m = 9 / 0.6
m = 15
Therefore, the rate of change of the linear function given in the table is 15.
Answer: D. m=15
