Step-by-Step Solution

To solve this problem, we'll determine the slope of the line that passes through the points A(0,10) A(0, 10) and B(5,0) B(5, 0) . The slope of a line passing through two points (x1,y1)(x_1, y_1) and (x2,y2)(x_2, y_2) is given by:

m=y2y1x2x1 m = \frac{y_2 - y_1}{x_2 - x_1} .

We identify the coordinates of our points:

  • (x1,y1)=(5,0) (x_1, y_1) = (5, 0)
  • (x2,y2)=(0,10) (x_2, y_2) = (0, 10) .

Substitute these coordinates into the slope formula:

m=10005 m = \frac{10 - 0}{0 - 5} .

Simplifying the equation gives:

m=105=2 m = \frac{10}{-5} = -2 .

Thus, the slope of the line is 2 -2 .

Therefore, the solution to the problem is m=2 m = -2 .

Answer

2 -2
