Work Step by Step
a) $W(0) = 8(0) + 700 = 700$ [when $g = 0$]
$W(250) = 8(250) + 700 = 2700$ [when $g = 250$]
On the x-axis (horizontal), you would have $g$ representing the number of gallons of water, ranging from $0$ to $250$. On the y-axis (vertical), you would have W representing the total weight in pounds. The values on the y-axis will range from $700$ to $2700$.
b) The y-intercept of $700$ suggests that even with no water, there's some weight (perhaps the weight of the empty spa and a TV).
