Question:

Add the following accessor method to your Line class:

public double getSlope()

Returns the slope of this Line . The slope of a line between points (x₁, y₁) and (x₂, y₂) is equal to (y₂ − y₁) / (x₂ − x₁). If x₂ equals x₁ the denominator is zero and the slope is undefined, so you may throw an exception in this case.
