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 6 lbs of blueberries for $16.50.
Sketch a graph of the relationship between cost and pounds of blueberries.

Problem 3 From Unit 2 Lesson 12

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 From Unit 2 Lesson 11

The points $(2, - 4)$ , $(x, y)$ , $A$ , and $B$ all lie on the line. Find an equation relating $x$ and $y$ .

A graph of 2 triangles on a line on a coordinate grid.
