The equation y = -9.4x + 509.60 gives the price y of a particular model of television c months after the television first became available. what is the real-world meaning of the y-intercept?

Explanation:

The equation y = -9.4x + 509.60 is in the form y = mx+b, which is slope intercept form. In this case, we see that:

m = -9.4 is the slope

b = 509.60 is the y intercept

If we plugged x = 0 into the equation above, we would get y = 509.60

This means that after x = 0 months (aka the starting point), the price is about 509.60 dollars.
