Math Problem Statement

Which equations and/or functions represent the graphed line? Select three options.

Solution

To determine which equations or functions represent the graphed line, we need to analyze the slope and y-intercept of the line on the graph.

Step 1: Identifying Slope and Y-Intercept

  1. The line crosses the y-axis at y=4y = -4, so the y-intercept (bb) is -4.
  2. The line appears to rise by 1 unit for every 5 units it moves to the right, indicating a slope (mm) of 15\frac{1}{5}.

Step 2: Equation of the Line

Using the slope-intercept form y=mx+by = mx + b: y=15x4y = \frac{1}{5}x - 4

Step 3: Match with Provided Options

Now, let’s check the options given:

  1. Option 1: f(x)=15x4f(x) = \frac{1}{5}x - 4 — This matches our derived equation.
  2. Other options should also have the same slope and y-intercept to represent the same line.

If you want further help with other options listed, feel free to provide the details of the remaining options, and I can verify each one.

Would you like additional details on identifying slope and intercepts?
