    the fixed amount is the value of y when x = 0

    Barney wants to rent a tent. He has to pay a fixed base cost plus a daily rate for renting the tent. The table shows the amount of money, y, in dollars, that Barney has to pay for renting the tent for x days: Tent Rental Number of days (x) Rent (dollars) (y) 0 3 1 8 2 13 3 18 4 23 Which equation best shows the relationship between x and y? y = 5x + 3 y = x + 8 y = 5x + 8 y = x + 3

    your equation will be in the form y = mx + b let's find m first. when x increases by 1, what value does y increase by?

    do you see the pattern in the y values in the table?

    every y value increases by a certain number each time, what is that number?

    great, so that means our m value (slope) is 5 so right now we have y = 5x + b, now let's find b b is the y value when x = 0, so what is b?

    would it be 1/5

    m = 5, since y increases by 5 every time x increases by 1 right now, we have y = 5x + b, now we need to find b b is the y value when x = 0, so what is b?

    right, so b = 3 putting everything together: y = mx + b = 5x + 3 and that's our answer
