A line contains the two points plotted in the coordinate plane below.

Andrew [12]

Answer:

The slope would be 3.

Step-by-step explanation:

The formula for finding slope is $\frac{y1-y2}{x1-x2}$
We can plug these numbers into the equation by doing $\frac{1--5}{2-0}$
1--5 is equal to 1+5, which is 6.
2-0 is equal to 2.
$\frac{6}{2}$ is 3, which is how you get your answer.
I hope this helps! :)
