Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Identify the coordinates of the points.

  • Step 2: Apply the slope formula.

  • Step 3: Perform the arithmetic to calculate the slope.

Let's work through each step:

Step 1: Identify the given points:
Point A A is (0,7) (0, 7) and Point B B is (8,3) (8, -3) .

Step 2: Use the slope formula, which is: m=y2y1x2x1 m = \frac{y_2 - y_1}{x_2 - x_1}

Substituting the coordinates of points A A and B B :
Here, (x1,y1)=(0,7) (x_1, y_1) = (0, 7) and (x2,y2)=(8,3) (x_2, y_2) = (8, -3) .

Step 3: Calculate the slope:
m=3780=108=54 m = \frac{-3 - 7}{8 - 0} \\ = \frac{-10}{8} \\ = -\frac{5}{4}

Therefore, the slope of the graph is 54 -\frac{5}{4} .

Answer

54 -\frac{5}{4}
