Question

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

Answer 1

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 = mx + b`

In this equation the m or slope is `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 = `y/x`

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

Answer 2

See the explanation.

Explanation:

Graph:

`y=3x`

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

`y=3x+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`.

`"Points"`

`x=(-2),` `y=(-6)`

`x=0,` `y=0`

`x=2,` `y=6`

Plot the points and draw a straight line through them.
