# How do you graph #y=4x#?

##### 3 Answers

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

#### Explanation:

Graph

First, determine your slope and y-intercept.

(Your equation is in slope-intercept form)

Slope-intercept Form:

In your equation, the slope is

Because your **rises** **runs**.

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

Take for x any two numbers. Let the x be 1 and 2.

So, according to the equation the results for the y would be as follows:

#### Explanation:

The number in front of the

The value of 4 is really

If the number in front of the x (coefficient) is positive the 'slope' goes up. If the coefficient is negative it means the 'slope' is down.

For this question; substitute any value you chose into

Mark your two points on the graph paper. Draw a line through them extending it to the edges of the axis.

The label could read something like:
