Answer:
x and y do not show direct variation.
Step-by-step explanation:
The formula for direct variation is
y = kx Divide each side by y
k = y/x
k should have the same value for every point except, of course, (0,0)
For the first point,
k = 2/(-1) = -2
For the third point,
k = 2/1 = 2
The values of k are different, so x and y <em>do not</em> show direct variation.
14-20= - 6
5/7x-6=4/7x-4
5/7x-4/7x= 1/7x
1/7x-6=-4
-4+6= 2
1/7x divide by 2= so x= 14
The graph passes through the points (2,2) and (6,6)
This means
f(2) = 2
f(6) = 6
The average rate of change of f(x) x = 2 to x = 6 will be:
Thus the average rate of change of given function from x = 2 to x = 6 is 1
Hi there! The answer is 7 1 / 2
