Linear Relationships

The graph shown has a positive slope.

• TRUE

• FALSE

What is the y-intercept (vertical intercept) of the graph?

• 0

• 8

• 16

• 32

What does the point (6, 32) explain about the situation?

• At 6 flags, the cost will be $32.

• At 6 seconds, the flag height will be 32 feet.

• The flag travels about 5.33 feet per second

• At 32 seconds, the flag height will be 6 feet.

Which of the following are true about a linear relationship? Select all that apply.

• The relationship has a constant slope (same rate throughout).

• The graph of the relationship will appear as a straight line.

• The slope of the line will always be positive.

• The slope of the line will always be negative.

• The graph will always start at the point (0, 0).

The line on this graph has a negative slope. Why?

• It actually has a positive slope, because the line is in the quadrant with positive coordinates.

• It is a negative slope because the line slants downward from left to right.

• It is a negative slope because the graph has negative numbers on the axes.

• It's actually a line with a positive AND negative slope, because the line has arrows on both ends.

What is the slope of this line?

• $\frac{5}{6}$

• $\frac{1}{3}$

• $3$

• $-\frac{1}{3}$

Horse A ran at a speed of 5.5 meters per second. Horse B ran 9 meters in 2 seconds. Which horse ran faster, and why?

• Horse B was faster because Horse A started at -2 meters.

• Horse A was faster because 5.5 meters per second is faster than 4.5 meters per second.

• Horse A was faster because Horse B started at 0 meters.

• Horse B was faster because the graph is in a straight line.
