Question

What is the slope of the line that passes through the pair of points? (1, 7), (10, 1) Question 19 options: 2/3 -2/3 3/2 -3/2

Answer 1

Slope is defined simply as delta y over delta x or the change in y over the change of x. We need to decided what points is going to be the start or the end. Typically, the point farther to the right of the graph is considered the end point.

Start: (1, 7)

End: (10, 1)

$m = \frac{1 - 7}{10 - 1} \\\\\\m = \frac{-6}{9} \\\\\\m = \frac{-2}{3}$
