. I. The graphs of all linear relationships are a line. • II. The graphs of all linear relationships go through the origin.
III. The tables of all linear relationships have a constant rate of change.
• IV. The tables of all linear relationships contain the point (0,0).
Which of the statements above are true?
I and III only
I, II, and Ill only
II and IV only
I, II, III, and IV

Step-by-step explanation:

The graph of a linear relationship consists of the x and y values. The y values are plotted on the vertical axis against the x values on the horizontal axis. A change in the values of x lead to a corresponding change in the value of y. The correct options are

. I. The graphs of all linear relationships are a line. They are sometimes called straight line graphs

III. The tables of all linear relationships have a constant rate of change. This represents the slope

The true statement is

I and III only
