The slope of f (x) is 10 because on the y-value side you add 10 each time and one the x-value side you add 1 each time, so the resulting slope is 10. The slope of g (x) is 5. F (x) has the least y-intercept because when x is 0, y is - 1. In g (x) the y-intercept is 1, so f (x) has the least y-Intercept.
