To bake one cake, drew uses 18 ounces of flour. he has 850 ounces of flour. let y represent the ounces of flour left and x represent the number of cakes he has baked. when the situation is modeled on a graph, what are the slope and the y-intercept of the line representing this situation? slope = 850 and y-intercept = 18 slope = 18 and y-intercept = 850 slope = -18 and y-intercept = 850 slope = 850 and y-intercept = -18
