A) the function that has the y-intercept closest to 0 is function 1. I know that because you can see it on the graph. For function 1, the y-intercept is (0,1).
B) the function with the greatest slope is function 3 because its slope is 5.
C) only function 3 has a slope greater than 2 because all of the other functions have a slope of 1 or have negative slopes.
