• 3/4 which is the slope of hypotenuse of triangle DEF.

• 4/3 which is the slope of triangle DEF.

• -1 which is the same as the slope of triangle DEF.

Which statement is not true?

Triangle MNP and JKL are similar right triangles. Between which pairs of points are the slopes the same? Choose all that apply.

• N and P; K and J

• M and P; J and L

• M and N; K and L

• N and P; J and L

Triangle HJK and triangle PMK are similar right triangles. The coordinates of all the verticces are integers. Which statement is true about the slope of line HK and the slope of line PK.

• The slope of line HK is less than the slope of line PK because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is less for line HK than it is for line PK.

• The slope of line HK is equal to the slope of line PK because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is the same for line HK as it is for line PK.

• The slope of line HK is greater than the slope of line PK because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is greater for line HK than it is for line PK.

• The relationship between the slope of line HK and the slope of line PK cannot be determined because the traingles are congruent.
