The set of y-values that you already know in the relationship y = mx + b.
If the range of known_y's is in a single column, each column of known_x's is interpreted as a separate variable.
If the range of known_y's is contained in a single row, each row of known_x's is interpreted as a separate variable.
known_x: any
Optional. A set of x-values that you may already know in the relationship y = mx + b.
The range of known_x's can include one or more sets of variables. If only one variable is used, known_y's and known_x's can be ranges of any shape, as long as they have equal dimensions. If more than one variable is used, known_y's must be a vector (that is, a range with a height of one row or a width of one column).
If known_x's is omitted, it is assumed to be the array {1,2,3,...} that is the same size as known_y's.
Returns the parameters of a linear trend.
