6. Prove that linear functions grow by equal differences over equal intervals.
Part I. This is the graph of. Use the graph to show that equal intervals of x-values have equal differences
of y-values.
a) Think about an interval on the x-axis starting with p and ending with p + k. What is the difference
between the x-values? What is the difference between the y-values for these x-values? Complete the
tables using.
