What is the slope of the line that goes through the points (2,-1) and (6,1)

drek231 [11]

Answer: The slope is $\frac{1}{2}$ .

Step-by-step explanation:

1. You set up your Slope Formula $M=\frac{y2-y1}{x2-x1}$ .

2. Substitue your points into the formula. $M=\frac{1--1}{6-2}$ .

3. Once you substitute, you will solve the equation $M=\frac{2}{4}$ .

4. Simplify the equation if you have to $M=\frac{1}{2\\}$ .
