The equation of this type of line is y = kx. What is special about k?
which represents Nikiya’s total cost✔ cost per hourtime spent talking
Base on these results, the runner ran at a rate between 0.5 and 2 hours than between 1.5 and 2.5 hours.
The ratios
Based on the graph shown to the right, whose phone cost varies directly with the amount of time spent talking? Mark’s only✔ Nikiya’s onlyboth Mark’s and Nikiya’s
Mark’s cost does not vary directly with time spent talking because the cost for t = 0 is undefined✔ the cost of 0 hours is not 0 dollarsthe C-intercept is 0
