# How do you graph y=4x+4 using rise over run?

Nov 12, 2017

The "rise over run" method is used for the slope, and you start at the $c$-value.

#### Explanation:

This function is linear. This means that the graph will be a straight line.

The rise and run method is only valid for the slope.

The slope is the term with the variable, in this case, $4 x$.

Rise and run is also useful for slopes with a fraction, with the numerator being the "rise" and the denominator being the "run". All whole numbers are a fraction with the denominator being $1$.

Therefore, in this case, the rise is by $4$, and the run is by $1$ to the right.

Where we start is the $c$-value. In this case, it is $4$.

From $4$ on the $y$-axis, count up $4 \mathmr{and} 1$ to the right. Mark the point. Repeat this a few times until you have a line of points and join them.

Put all this together and we get a graph looking like this:

graph{y=4x+4 [-10, 10, -5, 5]}

Hope this helps :)
