    Find the slope and y-intercept for each line that has a slope and y-intercept

    # 25 x + y = 5 # 47 x 3y #55 3
    -- = --- y = --x --2
    2 5 4

    Write a formula that describes the function for each of the following.

    # 7 A small pizza cost $ 5.00 plus 50 cents for each topping Express the total cost C as a function of the number of topping t.

    #9 The sales tax rate on groceries in Mayberry is 9%. Express the total cost T ( including tax ) as a function of the total price of the groceries S.

    # 82 Cost and toppings. The cost c in dollars for a pizza with n topping is given by

    C(n) = 0.75n + 6.99

    a) Find c(2), c(4),and c(5).
    b) Is the cost increasing or decreasing as the number of topping increases?

    Find the slope and y-intercept for each line that has a slope and y-intercept

    # 25 x + y = 5

    Y = 5 -x

    Slope = -1, and y-intercept = 5

    47)

    y =

    Since this would give us a horizontal line, then the slope = 0, no y-intercept

    55) y =

    Slope = ¾, y-intercept = -2

    Write a formula that describes the function for each of the following.

    # 7 A ...
