Math Problem Statement

Which statement is true? The slope of Function A is greater than the slope of Function B or The slope of Function A is less than the slope of Function B.

Solution

To solve this problem, we need to compare the slopes of Function A and Function B.

Analyzing the Functions:

Function A is given as: y=3x5y = 3x - 5

This is a linear equation in the slope-intercept form y=mx+by = mx + b, where mm is the slope and bb is the y-intercept. For Function A:

  • The slope m=3m = 3.

Function B is represented graphically. To find its slope, we need to identify two points on the line and use the slope formula:

slope=y2y1x2x1\text{slope} = \frac{y_2 - y_1}{x_2 - x_1}

Identifying Points for Function B:

From the graph:

  • The line passes through the points (0,2)(0, -2) and (2,4)(2, 4).

Now, let's calculate the slope of Function B:

slope of Function B=4(2)20=62=3\text{slope of Function B} = \frac{4 - (-2)}{2 - 0} = \frac{6}{2} = 3

Comparing Slopes:

  • Slope of Function A = 3
  • Slope of Function B = 3

Since both slopes are equal, the statement "The slope of Function A is greater than the slope of Function B" is false, and the statement "The slope of Function A is less than the slope of Function B" is also false. Therefore, neither of the provided options is correct based on the information given.

Relative Questions:

  1. What does the slope of a line represent in a real-world context?
  2. How can you determine if two lines are parallel by looking at their equations?
  3. How would the graph of a line change if the slope were negative?
  4. What is the y-intercept of Function A, and how does it affect its graph?
  5. How can you write the equation of a line given its slope and one point on the line?

Tip: When comparing slopes, remember that the greater the absolute value of the slope, the steeper the line.
