Mathematics
Coordinate Geometry: Distance, Midpoint and Slope
Students use the distance, midpoint and slope formulas to find lengths and centers, test whether a triangle is isosceles, and check a rectangle’s diagonals.

Mathematics
Finding Slope from Two Points
Students calculate slope from pairs of points, interpret positive, negative, zero and undefined slopes, complete a table, and find a mistake in sample work.
Science
Reading Motion Data: Velocity-Time and Position-Time Tables
Students read two data tables for a moving object, find acceleration from slopes, find distance from areas, and sketch the graph.
Mathematics
Slope and Linear Relationships from Points and Tables
Students find slope from two points and from tables, write y = mx + b equations, and interpret slope in real situations.
Mathematics
Slope-Intercept Form: Read It, Write It, Use It
Students read slope and y-intercept from equations, write equations in y = mx + b form from given information, and interpret a real-world line.
