The hiking club is taking another trip. The hike leaders watch shows that they gained 296 feet in altitude from there starting position.

Their altitude is now 285 feet, but there is no record of their starting altitude.

Write and solve and equation to represent this situation and find their starting altitude.

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,

there should be an link icon on the bottom of the text box you get. it looks like a paperclip!
