Lesson 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 you-pick blueberry farm offers 6 lbs of blueberries for $16.50.

Sketch a graph of the relationship between cost and pounds of blueberries.

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

1. $(0,3.5)$
2. $(12,11)$
3. $(80,50)$
4. $(\text-1,2.875)$

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

$\text-x<5$

$4x>\text-20$

$4x < \text-20$

$x < \text-5$

$x>5$

$x>\text-5$
