• Write the slope formula.
• Write the probability formula.

Definitions

• Define ordered pair.
• Define domain.
• Define range.
• Define function.
• Define arithmetic progression.
• Define probability.

Direct Substitution Practice

• If a = 3, d = 2, find the 5th term of the AP.
• Find the midpoint of (2, 4) and (6, 8).
• Find the slope of the line joining (1, 2) and (3, 6).
• Find the probability of getting a head when a coin is tossed once.
• Find the volume of a cylinder with radius r and height h.

Graph and Geometry Quick Checks
