Question 1 of 2

Graph the line y = −2x + 5. What is the y-intercept?

Question 2 of 2

A line passes through the points (0, −3) and (2, 1). What is the slope of this line?

How this fits in

Graphing lines from equations is one skill in the Linear Functions unit. Students read the unit lesson, then earn a bronze, silver, or gold medal on their last 10 answers. Medals never go down. A mastered unit comes back for review after 1, 3, 7, 16, and 35 days so it stays learned.
