Final answer:
A linear function can be represented as a picture, a graph, a table, an equation or expression, and a word problem.
Step-by-step explanation:
A linear function can be represented in various ways:
- Picture: A linear function can be represented as a picture by graphing it on a coordinate plane. The graph will form a straight line, with the y-intercept representing the starting point of the line and the slope representing the rate of change.
- Graph: A linear function can be represented graphically by plotting the coordinates of points that satisfy the equation. Connect these points with a straight line to create the graph of the function.
- Table: A linear function can also be represented in a table by listing the input (x) and output (y) values that satisfy the equation. Each x-value is paired with its corresponding y-value.
- Equation or Expression: The equation or expression of a linear function is of the form y = mx + b, where m is the slope and b is the y-intercept. This equation represents the relationship between the input and output values of the function.
- Word Problem: A linear function can be represented in the form of a word problem, where the equation or expression describes a real-life situation. The variables in the equation represent different quantities and their relationships.
