Question

Find the slope of the line passing through the given points, when possible. (If an answer is undefined, enter UNDEFINED.)

(− 3/10, − 1/5) and ( 3/8, 8/5)

Answer 1

8/3

Explanation:

The slope is rise/run.

This line rises 8/5 - (-1/5), and 'runs' 3/8 - (-3/10).

That simplifies to 9/5 and 27/40.

That means the slope is (9/5)/(27/40), which simplifies to 8/3
