What is the equation 3y – 6x = 9 written in the form y=mx+b ?

a. y = 2x + 3
b. y = 18x + 21
c. y = 3 – 2x
d. y = 6x + 9

A. y = 2x + 3

Step-by-step explanation:

3y – 6x = 9

+ 6x + 6x

3y = 6x + 9

y = 2x + 3 >> CORRECT ANSWER

I am joyous to assist you anytime.

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
