These are linear functions: Identifying Linear Functions from a Graph These are linear functions: These are NOT:

These are linear functions: Identifying Linear Functions from an Equation These are linear functions: These are NOT:

Linear graphs… form a line.

Linear equations… x and y both have exponents of 1. x and y are not multiplied together. x and y do not appear in denominators, exponents, or radical signs.

The points from this table lie on a line. Identifying Linear Functions from a Table of Values The points from this table lie on a line. LINEAR

The points from this table do not lie on a line. Identifying Linear Functions from Tables of Values The points from this table do not lie on a line. NON-LINEAR

Tell whether each set of ordered pairs satisfies a linear function. YOU TRY Tell whether each set of ordered pairs satisfies a linear function. 1. {(–3, 10), (–1, 9), (1, 7), (3, 4), (5, 0)} 2. {(3, 4), (5, 7), (7, 10), (9, 13), (11, 16)} Tell whether each function is linear. If so, graph the function. 3. y = 3 – 2x 4. x + 3y = 12
