Triangle LMN and triangle QRS are similar right triangles. Based on the information, which statement about slope is true?

• The slope of QS is equal to the slope of LN because they lie on the same line.

• The slope of QS is less than the slope of LN because triangle QRS is smaller than triangle LMN.

• The slope of LN is greater than the slope of QS because the points of LN are farther apart than the points of QS.

• There is no relationship between the slope of QS and the slope of LN.
