A photographer charges $20 for an 8 x 10 photo plus a sitting fee. Luann
spent $55 on two 8 x 10 photographs
and the sitting fee. Assume the
relationship is linear. Find and interpret
the rate of change and the initial value.

Atriangle with all sides of equal length is a/an triangle. a. right b. scalene c. equilateral d. isosceles

The equation shown below represents function f. f(x)= -2x+5 the graph shown below represents function g. which of the following statements is true? a. over the interval [2, 4], the average rate of change of f is the same as the average rate of change of g. the y-intercept of function f is less than the y-intercept of function g. b. over the interval [2, 4], the average rate of change of f is greater than the average rate of change of g. the y-intercept of function f is greater than the y-intercept of function g. c. over the interval [2, 4], the average rate of change of f is the same as the average rate of change of g. the y-intercept of function f is greater than the y-intercept of function g. d. over the interval [2, 4], the average rate of change of f is less than the average rate of change of g. the y-intercept of function f is the same as the y-intercept of function g.
