- Constructor Detail
 - SlopeInterceptLine2D
```
SlopeInterceptLine2D(Double slope, Double yIntercept, Function2<Double, Double, P> createPoint)
```
 Creates a non-vertical line given its slope and yIntercept.
 - SlopeInterceptLine2D
```
SlopeInterceptLine2D(Double xIntercept, Function2<Double, Double, P> createPoint)
```
 Creates a vertical line given its xIntercept.
- Method Detail
 - isHorizontal
```
 Boolean isHorizontal()
```
 Indicates if the line is aligned to the x-axis.
 - isVertical
```
 Boolean isVertical()
```
 Indicates if the line is aligned to the y-axis.
 - getSlope
```
 Double getSlope()
```
 The slope of the line, if isVertical this is undefined (= Double.NaN).
 - getYIntercept
```
 Double getYIntercept()
```
 The y-coordinate of the y-intercept (= the point where the line intersects the y-axis). If isVertical there's no y-intercept and this is Double.NaN. The slope-intercept representation (y = mx + b) uses this intercept.
 - getXIntercept
```
 Double getXIntercept()
```
 The x-coordinate of the x-intercept (= the point where the line intersects the x-axis). If isHorizontal there's no x-intercept and this is Double.NaN.
 - contains
```
 Boolean contains(P point)
```
 Checks if the point belongs to this line.
 - findY
```
 final Double findY(Double x)
```
 Solves the line equation for the given x. Throws an UnsupportedOperationException if the line isVertical.
 - findPoint
```
 P findPoint(Double x)
```
 Finds the point belonging to the line with the given x-coordinate. Throws an UnsupportedOperationException if the line isVertical.
 - isParallelTo
```
 Boolean isParallelTo(Line2D other)
```
 Checks if two lines are parallel.
 - coincidesWith
```
 final Boolean coincidesWith(Line2D<?> other)
```
 Checks if two lines coincide.
 - intersect
```
 Intersection2D intersect(Line2D other)
```
 Intersects two lines.
 - intersectCircle
```
 Intersection2D intersectCircle(P center, Double radius)
```
 Intersects a line and a circle. Radius must be positive. Intersection is performed by plugging the line equation in the circle equation and solving the resulting quadratic equation. Circle equation: (x - center.x)^2 + (y - center.y)^2 = r^2. Line equation: y = slope * x + yIntercept unless isVertical, x = xIntercept otherwise.
 - equals
```
 Boolean equals(Object other)
```
 Checks if other is a Line2D and if it coincidesWith this one.
 - hashCode
```
 Integer hashCode()
```
 Uses slope, yIntercept and xIntercept.
