Math Problem Statement

Solve

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 solve the problem by analyzing the slopes of both functions, AA and BB.

Function A:

From the graph of Function A, we can calculate the slope by identifying two points on the line. The slope is calculated as: slope=ΔyΔx=y2y1x2x1\text{slope} = \frac{\Delta y}{\Delta x} = \frac{y_2 - y_1}{x_2 - x_1}

Looking at the graph:

  • One point is (0,0)(0, 0) (the origin).
  • Another point is (2,4)(2, 4).

So, the slope of Function A is: slope of A=4020=42=2\text{slope of A} = \frac{4 - 0}{2 - 0} = \frac{4}{2} = 2

Function B:

To calculate the slope of Function B, we will use the two points from the table provided:

  • (4,14)(-4, -14)
  • (2,6)(-2, -6)

The slope formula for Function B is: slope of B=6(14)2(4)=6+142+4=82=4\text{slope of B} = \frac{-6 - (-14)}{-2 - (-4)} = \frac{-6 + 14}{-2 + 4} = \frac{8}{2} = 4

Comparison:

  • The slope of Function A is 22.
  • The slope of Function B is 44.

Thus, the correct statement is: The slope of Function A is less than the slope of Function B.
