get_intersection | R Documentation |

Get the intersection point of two straight lines given in slope–intercept form.

```
get_intersection(x, y)
```

`x` |
A named vector with intercept ["a"] and slope ["b"]. |

`y` |
A named vector with intercept ["a"] and slope ["b"]. |

A named vector giving the intersection, `NULL`

if the
lines do not intersect, `NaN`

if they are identical.

Other geometry functions:
`points2equation()`

,
`vector_length()`

```
get_intersection(x = c(a = 0, b = 1), y = c(a = 2, b = -1))
get_intersection(x = c(a = 0, b = 1), y = c(a = 2, b = 1))
x <- c(a = 0, b = 1)
get_intersection(x = x, y = x)
```
