Write an equation that can be used to calculate d, the distance traveled by Anthony in m minutes. Use your equation to determine how far Anthony will have run after 7 minutes.

d = 200m

1400 m.

Step-by-step explanation:

This is direct variation.

At time 0 distance  run is zero.

d = km where d = distance, m = time and k is a constant.

k = the slope of the line joining the points and is  

800 / 4

= 200.

So the equation is d= 200m.

After 7 minutes he has run 20*7

= 1400 meters.

step-by-step explanation:

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
