# How do you graph the line given (2, -1) with slope of 3?

Apr 25, 2016

You plot the coordinates then use the slope of $3$ as $\frac{3}{1}$

#### Explanation:

To plot the point, move $2$ to the right on the $x$-axis then $1$ down ($y$-axis). Then look at the slope. $3$ is also equal to $\frac{3}{1}$ (3 over 1) as a fraction.

In a fraction there are two parts, the numerator (top number in this case $3$) and the denominator (bottom number in this case $1$).

The numerator shows the rise (number of spaces you go along the $y$-axis) and the denominator shows the run (number of spaces you go along the $x$-axis).

So from the point $\left(2 , - 1\right)$, you go up (since it is a positive slope) $3$ spaces and to the right $1$ space.
