Select all that apply. A relationship between two variables is a function if each value of one variable (the independent variable) is related to exactly one value of the second variable (the dependent variable). Answer: Y=2. Since the function is a line, the graph (and table of values) will have a CONSTANT RATE OF CHANGE This constant rate of change is known as SLOPE. We need a thorough and flexible understanding of these forms in order to approach many SAT questions about linear relationships. 8.F.A.3 — Interpret the equation y = mx + b as defining a linear function, whose graph is a straight line; give examples of functions that are not linear.

Step 2: Solve for the limit of the function, using some basic properties of linear functions: The limit of ax as x tends to c is equal to ac. Solving Real-Life Problems using Linear Equations. Understand that a function is linear if it can be expressed in the form f(x) = mx + b or if its graph is a straight line.Example: The function f (x) = x 2 is not a linear function because its graph contains the points (1,1), (-1,1) and (0,0), which are not on a straight line. To understand applications of linear equations we need to have an understanding of slope, how to interpret a graph, and how to write an equation. Or, put in other words, we will now start looking at story problems or word problems. Class Date 5.1 Understanding Linear .
