Question 1 of 3

A line passes through points A(2, 5) and B(6, 13). What is the slope of line AB?

Question 2 of 3

A line segment connects point P(−3, 4) and point Q(5, −8). What is the slope of line PQ?

Question 3 of 3

Find the distance between points D(−5, 2) and E(3, −4).

How this fits in

Area and perimeter on the coordinate plane is one skill in the Coordinate Geometry 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.
