Question

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?

Answer 1

X = number of cakes baked

18x = ounces of flour used

850 - 18x = ounces of flour left = y

y = 850 -18x

slope = -18 .... [ the negative value of the ounces of flour used]

y-intercept = 850 -18 (0) = 850 -0 = 850 ... [the ounces of flour before making the first cake]

Answer 2

Answer:

C) slope = -18 and y-intercept = 850
