Mrs. Drew’s class is doing a survey of the 8 th grade students. They are collecting data of each student’s arrival time at school and each student’s assigned lunch time. When arrival time is the independent variable and lunch time is the dependent variable, is the relation a function or not a function?

The table below represents a linear function f(x) and the equation represents a function g(x): x f(x) −1 −5 0 −1 1 3 g(x) g(x) = 2x − 7 part a: write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points) part b: which function has a greater y-intercept? justify your answer. (4 points)
