Martin modeled the distance, y, that runners traveled during a race as a function of the time, x, that they ran. Which would best describe the domain of this function? A. all integers

B. all real numbers

C. all positive integers

D. all positive real numbers

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
