Can you find the equations for A and B?

A. y=1/-2x+5

B. y=1/2x

Step-by-step explanation:

the y-intercept of line A is 5, so the slope, or the rise/run, is 1/-2. A similar thing for line B; the y-intercept is 0 and the slope is 1/2/

gregory's graph is incorrect because it shows 2 inches of growth for each week when it should show 0.75 inches of growth each week.

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,
