1A Describing and Graphing Situations

The vertical axis of a line graph is called the __________.

• slope

• line of best fit

• x-axis

• y-axis

A ____________ shows the overall trend of all the data taken in an experiment.

• line of best fit

• slope

• position

• direction

A _________ is a pair of numbers used to determine the position of a point on a graph.

• coordinate

• line of best fit

• straight

• x-axis

The slope of the graph tells you how much y changes for every change in x.

• true

• false
