Lesson 1: Practice Problems

Problem 1

Priya jogs at a constant speed. The relationship between her distance and time is shown on the graph. Diego bikes at a constant speed twice as fast as Priya. Sketch a graph showing the relationship between Diego’s distance and time.

A graph of time (hours) vs distance (miles) with a line starting at (0,0).

Problem 2

A you-pick blueberry farm offers 5 lbs of blueberries for $24.
Sketch a graph of the relationship between cost and pounds of blueberries.

Problem 3 From Unit 2 Lesson 17

A line contains the points $(- 4, 1)$ and $(4, 6)$ . Decide whether or not each of these points is also on the line:

$(0, 3.5)$
$(12, 11)$
$(80, 50)$
$(- 1, 2.875)$

Problem 4

Select all the inequalities that have the same solutions as $- 4 x < 20$ .

$- x < 5$
$4 x > - 20$
$4 x < - 20$
$x < - 5$
$x > 5$
$x > - 5$
