A Fraction of a Slope

Part of the Graphs & Systems section of Coddy's Algebra journey. Lesson 12 of 61.

A slope does not have to be a whole number. For the line through (0, -1) and (6, 3), the formula gives:

m=3+16+0=46=23m = \frac{3+1}{6+0} = \frac{4}{6} = \frac{2}{3}

Leave the answer as the reduced fraction 23\frac{2}{3}. Do not round it to a decimal. A slope of 23\frac{2}{3} means the line goes up 2 for every 3 steps right, and that is exact. A slope of 32\frac{3}{2} means up 3 for every 2 steps right, which is steeper.

Always reduce the fraction. The slopes 46\frac{4}{6}, 69\frac{6}{9} and 23\frac{2}{3} are all the same slope, written in three ways. When you reduce each one, you can see that they are equal. Give the reduced form as your answer.
