# What is the slope and intercept for y=3x and how would you graph it?

Oct 6, 2015

The slope would be $3 x$ and the y-intercept would be $0$.

#### Explanation:

1)Slope intercept form is $y = m x + b$.

2)Your form is also in $y = m x + b$ but is simply
missing the $b$ portion of it. So your equation is $y = m x$
$m = s l o p e$. $x =$x-intercept.

3)You would begin by graphing the y-intercept, which in this case is $0$. Graph the point at (0,0)

4)Because the slope is positive, you would have a line that slants to the right. Slope is rise/run and $3 x$ is the same thing as $\frac{3}{1}$.

5)Go up three units and over one unit (making sure you are going to the right of the (0,0) point.

6)Continue to graph, following the pattern, 3 up, 1 over, plotting the points as you go.
