Question

A restaurant menu shows the price for 2 chicken wings is $2.30 and the price for 6 chicken wings is $6.90. The function below gives the price, y, for x wing

y - 2.30 = 1.15(x - 2)
If this function is graphed in the coordinate plane, what is the y-intercept?

Answer 1

y - intercept = 0 [(0,0)]

Explanation:

Given the equation y - 2.30 = 1.15(x-2), the y-intercept is when x is 0.

So to find your answer, just substitute in 0 for x, and solve for y:

y - 2.30 = 1.15(x - 2) →

x = 0

y - 2.30 = 1.15(0 - 2) →

y - 2.30 = 1.15(-2)

y - 2.30 = -2.30 →

+2.30 +2.30

y = 0
