Linear Relations

The first differences of a linear relation are always the same.

• True

• False

• Depends on the question

The height of a skydiver over time is shown in the table. Is the relation linear?

• Yes

• No

Is this graph linear?

• Yes

• No

If the first differences are NOT the same, the relation is __________.

• Linear

• Non-linear

Another name for the rate of change of a linear relation is:

• the slope

• the y-intercept

• none of the above

• all of the above

This linear relation has

• a negative slope

• a positive slope

The higher the slope of a line, the _______________ the line.

• further down

• further up

• less steep

• more steep

Slope is calculated by

•  $\frac{run}{rise}$

• $\frac{rise}{run}$

• finding the point where the line crosses the y-axis

• finding the point where the line crosses the x-axis

What is the rate of change for the following graph?

• 80
• 20
• 40
• 160
