The distance between r and t on the coordinate grid is units. (input whole numbers only.) image of a coordinate grid with point r r located at negative 30, 10 and point t located at 15, 10.

the distance between the R and the T is

4 units

its the fourth option

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,
