Find the slope of the line that passes through the pair of points.

(1, 7), (10, 1)

1 answer

To find the slope of the line that passes through the points \((1, 7)\) and \((10, 1)\), we can use the formula for the slope \(m\) between two points \((x_1, y_1)\) and \((x_2, y_2)\):

\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]

Here, the coordinates of the points are:

  • \((x_1, y_1) = (1, 7)\)
  • \((x_2, y_2) = (10, 1)\)

Now, we can substitute the values into the slope formula:

\[ m = \frac{1 - 7}{10 - 1} \]

Calculating the values in the numerator and denominator:

\[ m = \frac{-6}{9} \]

Now simplify the fraction:

\[ m = -\frac{2}{3} \]

Thus, the slope of the line that passes through the points \((1, 7)\) and \((10, 1)\) is \(\boxed{-\frac{2}{3}}\).
