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 \(\text-4x<20\).

\(\text-x<5\)

\(4x>\text-20\)

\(4x < \text-20\)

\(x < \text-5\)

\(x>5\)

\(x>\text-5\)
