Math Slope in Triangles

Two similar right triangles are shown in the coordinate plane. Point P lies on line segment PR. Which statement best compares the slope of PQ to the slope of PR.

• PQ and PR have the same length, so the slopes must be equal.

• The lengths of the corresponding legs of the two triangles are proportional because they are similar, so the slopes must be equal.

• The horizontal distance from P to Q is 2 units, but the vertical distance is 4 units, so the slopes can't be equal.

• The short leg of the large triangle is the same length as the long leg of the small triangle, so the slopes cannot be equal.

What is the slope of the line shown by the similar triangles in the graph?

• -4/3 = -8/6 = /4/3

• -4/-3 = -8/-6 = 4/3

• 3/-4 = 6/-8 = -3/4

• 3/4 = 6/8 = 3/4
