The cost y (in dollars) to rent a kayak is proportional to the number x of hours that you rent the kayak. It costs $27 to rent the kayak for 3 hours. a. Write an equation that represents the situation.

If the cost y is proportional to the number of hours x:

y = kx   where k is the constant of proportion.

Given $27 for 3 hours, find k

27 = 3k

k = 9

Your equation is:  y = 9x

From this, given a value for y or x you can plug it in to find the other.

Step-by-step explanation:

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
