Watermelon has 2 grams of carbohydrates per ounce.
We are preparing a fruit salad and we want the total carbohydrates from pineapple and watermelon to equal 24 grams. How can we show this combination with a graph? Well, let's make a plan!
Write an Equation
The equation should give us the total amount of carbohydrates equal to 24 grams. Let x be the weight of pineapple and y be the weight of watermelon in ounces. We can use this information to write an equation.
3x+ 2y= 24
Domain and Range of the Equation
In order to find reasonable domain and range, let's start with finding the intersection points of the equation. We can find the x-intercept by substituting 0 with y into the equation.
We have found that the y-intercept is equal to 12. Since the minimum amount of pineapple and watermelon we can use is 0 grams, the domain and range will begin with zero grams and end with the intercepts.
Domain:&[0,8]
Range:&[0,12]
Finally, let's graph the equation by plotting the intersection points and then connecting them.
