# How do you graph the equation y=3x?

Jun 30, 2017

Start at (0,0) move one place to the right and three places up, make a point, at (1,3) repeat and make another point at (2,6). Connect the points.

#### Explanation:

The y intercept form is $y = m x + b$

In this equation the m or slope is $\frac{3}{1}$

In this equation the b or y intercept is 0

the b or y intercept is 0 ( b think beginning ) so start at ( 0,0)

The slope m is the angle of the line think mountain slope.

So starting at ( 0,0) the b or beginning move over 1 and up 3

because the slope is 3 = $\frac{y}{x}$

Repeat this process at least twice, so that there are three points to connect to make a line.

See the explanation.

#### Explanation:

Graph:

$y = 3 x$

This equation is in slope intercept form, and can be rewritten as:

$y = 3 x + 0$, where $3$ is the slope and "0" is the y-intercept.

Determine a few points on the line by choosing values for $x$ and solve for $y$.

$\text{Points}$

$x = \left(- 2\right) ,$$y = \left(- 6\right)$

$x = 0 ,$$y = 0$

$x = 2 ,$$y = 6$

Plot the points and draw a straight line through them.
