Determine which expression(s) best describes the function, f(x) = 1/3 x -1. choose all that apply
a. given any two coordinates that lie on the graph of the function, the pythagorean theorem can be used to determine the midpoint of the function
b. the function has a x-intercept of (3, 0)
c. the function has a y-intercept of (0, -1)
d. the slope is sometimes consistent for any pair of coordinates that lie on the graph of the function
e. for a right triangle with a vertical side length of 1 unit and a horizontal side length of 3 units, if one point of the hypotenuse of the triangle is on the graph of the function, then so is the other
