Bill started west on road u. s. 50, riding a bicycle at an average rate of 9 mph. four hours later charles started after bill on a motor cycle and overtook him in 2 hours. what was charles' rate?

which equation could be used to solve for charles' rate if it is represented by x?
a.2x = 36
b.2x = 54
c.6x = 54

2x = 54

I got this question correct on my lesson.

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
