The cost of renting a kayak is represented by the equation
y = 8x + 5, where x represents the number of hours. What
does the slope of the equation represent?

Answer 1

9514 1404 393

Answer:

dollars per hour

Explanation:

If m is the slope, the units of m can be found by considering the units of x and y.

y is in dollars

x is in hours

Then from the point of view of units, we have ...

dollars = m × hours

m = dollars/hours

The slope in the equation is the rental charge in dollars per hour.
