Aiko types at a rate of 70 words per minute. After typing at the same rate for 3 minutes, he had typed a total of 210 words.

This situation can be represented with a linear equation written in point-slope form, where x represents the number of minutes and y represents the number of words.

  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).

hey seth! : )

i’m not 100% sure, but i think it’s b

hope this ya : p

miss u!
