Question

which of the following statements about line graphs is true?
A The dependent variable is on the horizontal axis.
B Line graphs are always straight lines.
C Every data point should be shown on a line graph.
D There is a maximum number of data points that can be used in a line graph.

Answer 1

The answer is A, the dependent variable is on the horizontal axis. Since in the equation 2x=y, the values of y is dependent of the value of x. Line graphs can be curves. Not all data points need to be shown, and there is no maximum number of data points.

Answer 2

Answer: Its actually C. every data point should be shown on a line graph

I just sent the test.
