The scatterplot shows the energy in watts and the light output in lumens per watt of several lightbulbs.
Which statement best describes the association between the energy and light output of these lightbulbs?
F As the energy increases, the light output increases.
G As the energy increases, the light output decreases.
H As the energy increases, the light output remains the same.
J There is no apparent association between the energy and light output.

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?
F 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.
G 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.
H 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.
J The relationship between the slope of HK and the slope of PK cannot be determined, because the triangles are congruent.
