Triangle `HJK`and triangle `PMK`are similar right triangles. The coordinates of all the vertices are integers.

Which statement is true about the slope of `HK`and the slope of `PK`?

• The slope of `HK`is less than the slope of `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 `HK`than it is for `PK`.

• The slope of `HK`is equal to the slope of `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 `HK`as it is for `PK`.

• The slope of `HK`is greater than the slope of `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 `HK`than it is for `PK`.

• The relationship between the slope of `HK`and the slope of `PK`cannot be determined, because the triangles are not congruent.
