Answer:
4 ($4.00)
Explanation:
Before finding the y-intercept of the line, we should first find an equation that represents the equation.
Total Price = Price of a Bowl of Yogurt + Price for Each additional topping.
The question tells us that total price should be represented as y and number of toppings be represented as x.
y = Price of a Bowl of Yogurt + 0.25x
We also know the price of a bowl of yogurt is $4, which means our equation is:
y = 4 + 0.25x
Notice how this equation is very similar to the slope-intercept form of a line.
y = mx + b
y = 0.25x + 4
Using these similarities, we can figure out the y-intercept of the line. In slope-intercept form, "b" represents the y-intercept. The similar term in our frozen yogurt equation is "4". This means the value of the y-intercept of the line representing this situation is 4.
