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

Let's analyze the information provided to determine the correct answer.

Step 1: Identify the slope of Function A

The equation for Function A is given as: y=4x4y = 4x - 4 In this form, y=mx+by = mx + b, where mm represents the slope. Here, the slope mm for Function A is 4.

Step 2: Calculate the slope of Function B

For Function B, we have a table of values:

  • When x=7x = -7, y=10y = -10
  • When x=6x = -6, y=8y = -8
  • When x=5x = 5, y=14y = 14

To find the slope mm of Function B, we use the slope formula: m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1} Let's pick two points, say (7,10)(-7, -10) and (6,8)(-6, -8): m=8(10)6(7)=8+106+7=21=2m = \frac{-8 - (-10)}{-6 - (-7)} = \frac{-8 + 10}{-6 + 7} = \frac{2}{1} = 2 Thus, the slope of Function B is 2.

Step 3: Compare the Slopes

  • Slope of Function A = 4
  • Slope of Function B = 2

Since 4 is greater than 2, the slope of Function A is greater than the slope of Function B.

Answer

The correct statement is:

  • The slope of Function A is greater than the slope of Function B.
