Question 11

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.

Accepted Answer

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.

Answer

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.

Answer

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.

Answer

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

Question 16

Which of the following is true about the triangles shown on the graph?

Accepted Answer

The slopes of the two triangles are the same.

Answer

The slope of the smaller triangle is smaller than the slope of the larger triangle.

Answer

The slope of the larger triangle is larger than the slope of the smaller triangle.

Answer

The triangles are congruent. Congruent: same size, same shape.

Question 17
