Recognizing the Question Type

Question type	What to look for
Linear equation in one variable	One unknown with a constant rate of change
Linear function	A line, slope, intercept, or constant rate in a table, graph, or equation
Linear equation in two variables	A relationship between two quantities that can be written in the form $Ax+By=C$
System of linear equations	Two linear relationships that must be true at the same time
Linear inequality	A range of possible values or words such as at least, at most, or no more than

Tip

Tip

Identify what the question asks for before calculating: one value, a rate, an intercept, an equation, an intersection, or a range. That target usually reveals the most direct algebraic method.
