00:00 A graph is a straight line through the point (0,5). Can the graph represent a proportional relationship? Explain.
А.
00:00
Yes, the constant of proportionality is 5.
O
B.
00:00
Yes; the equation of the line can
be written in the form y = kx, where k = 5.
C С.
00:00
Yes, the graph is a
straight line that crosses the y-axis at (0,5).
D
00:00
No: the graph of a
proportional relationship must pass through (0,0)

Two groups of students were asked how many hours they spent reading each day. the table below shows the numbers for each group: group a 1 2 1 1 3 3 2 2 3 group b 3 2 3 2 2 2 1 1 2 based on the table, which of the following is true? the interquartile range for group a students is 0.5 less than the interquartile range for group b students. the interquartile range for group a students is equal to the interquartile range for group b students. the interquartile range for group a employees is 0.5 more than to the interquartile range for group b students. the interquartile range for group a employees is 1 more than the interquartile range for group b students.
