Answer
a. To make a graph of the function make a table for x and y value of the function f(x) = -3x-9 and graph corresponding x and y values.
b. Slope = -3.
c. Rate of change = -3.
Work Step by Step
a. Plot the x and y values on a coordinate grid to graph the function.
b. The slope = the a value which in this case is -3.
c. The slope = rate of change so rate of change = -3.
