function lerp( x, y, t ) {

	return ( 1 - t ) * x + t * y;

}
Returns a value linearly interpolated from two known points based on the given interval -
`t = 0` will return `x` and `t = 1` will return `y`.

@param {number} x - The start point
@param {number} y - The end point.
@param {number} t - The interpolation factor in the closed interval `[0, 1]`.
@return {number} The interpolated value.
