Math Problem Statement

The graph of a linear function is shown. The slope of the linear function shown is ____. The y-intercept of the linear function is ____.

Solution

Let's analyze the graph to find the slope and y-intercept of the linear function.

  1. Finding the slope: The slope mm of a line is calculated as: m=change in ychange in x=ΔyΔxm = \frac{\text{change in } y}{\text{change in } x} = \frac{\Delta y}{\Delta x} Looking at the graph, we can observe two points:

    • One point is at (3,5)(-3, -5).
    • Another point is at (3,4)(3, 4).

    To find the slope: m=4(5)3(3)=4+53+3=96=32m = \frac{4 - (-5)}{3 - (-3)} = \frac{4 + 5}{3 + 3} = \frac{9}{6} = \frac{3}{2} So, the slope is 32\frac{3}{2}.

  2. Finding the y-intercept: The y-intercept is where the line crosses the y-axis. From the graph, we see that the line crosses the y-axis at y=1y = -1.

Thus:

  • The slope of the linear function is 32\frac{3}{2}.
  • The y-intercept of the linear function is 1-1.

Here are 5 related questions for further exploration:

  1. What is the equation of the line in slope-intercept form y=mx+by = mx + b?
  2. How does changing the slope affect the steepness of a line?
  3. What is the x-intercept of this line?
  4. How would the graph look if the slope was negative?
  5. Can a line have no y-intercept? If so, when?

Tip: When calculating the slope between two points, always remember to subtract the coordinates in the same order (i.e., Δy\Delta y and Δx\Delta x correspond to the same points).
