Parker drank one glass of chocolate milk and ate (x) cookies for a snack. The linear equation below represents the total number of calories in Parker's snack (y).
y=20x+238
a) What is the y-intercept of the line represented by this equation?
The y-intercept of an equation is the value of y when x is equal to 0. In this case, when x is 0:
y = 20(0) + 238
y = 0 + 238
y = 238
Therefore, the y-intercept of the line represented by the equation is 238.
