Which statement is true about the slopes of Function A and Function B?

Solution

Let's break this down step by step:

Function A:

Looking at the graph of Function A, we can determine the slope. The slope (mm) of a line is calculated as the change in yy divided by the change in xx, or:

m=ΔyΔxm = \frac{\Delta y}{\Delta x}

From the graph, let's take two clear points on the line. The line crosses the points (4,0)(-4, 0) and (0,2)(0, 2).

So the change in yy is: Δy=20=2\Delta y = 2 - 0 = 2 And the change in xx is: Δx=0(4)=4\Delta x = 0 - (-4) = 4 Thus, the slope of Function A is: mA=24=12m_A = \frac{2}{4} = \frac{1}{2}

Function B:

For Function B, we can calculate the slope using the given table. To find the slope, we use the formula:

m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1}

Let's take two points from the table, (4,24)(-4, -24) and (1,9)(-1, -9):

mB=9(24)1(4)=9+241+4=153=5m_B = \frac{-9 - (-24)}{-1 - (-4)} = \frac{-9 + 24}{-1 + 4} = \frac{15}{3} = 5

Comparing Slopes:

  • Slope of Function A: 12\frac{1}{2}
  • Slope of Function B: 55

Clearly, the slope of Function A is less than the slope of Function B.

Conclusion:

The correct statement is:

  • "The slope of Function A is less than the slope of Function B."

Tip: Remember that a positive slope means the line rises as xx increases, while a negative slope means it falls.
