Find an equation for the line with slope m=4/7 and which goes through the point (21,-7)

y=4/7x-19

Step-by-step explanation:

So the equation is :

y-=m(x-)

m= slope

y+7=4/7(x-21)

y=4/7x-19

HOPE I helped :D

  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).
