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).

Question

y=20x+238

a) What is the y-intercept of the line represented by this equation?

Answer 1

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.
