# How can you graph y x 3?

## How do you graph an equation?

To graph an equation using the slope and y-intercept, 1) Write the equation in the form y = mx + b to find the slope m and the y-intercept (0, b). 2) Next, plot the y-intercept. 3) From the y-intercept, move up or down and left or right, depending on whether the slope is positive or negative.

## What is the y-intercept of y =- 3x 3?

## How do I graph a line?

Graphing a Line Using the Slope and Y-Intercept
1. Find the y-intercept = b of the equation y = mx + b.
2. Plot the y-intercept. The point will be (0, b).
3. Find the slope=m of the equation y = mx + b.
4. Make a single step, using the rise and run from the slope. …
5. Connect those two points with your line.

## How do you draw a line graph?

To draw a line graph, first draw a horizontal and a vertical axis. Age should be plotted on the horizontal axis because it is independent. Height should be plotted on the vertical axis. Then look for the given data and plot a point for each pair of values.

## What is the slope of the graph of y =- 3x?

Using the slope-intercept form, the slope is −3 .

## Is the equation y 3x in slope intercept form?

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.

## How do u calculate the slope?

Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).

## How do you find the y-intercept?

Since the y-intercept always has a corresponding x-value of 0, replace x with 0 in the equation and solve for y. On a graph, the y-intercept can be found by finding the value of y when x=0. This is the point at which the graph crosses through the y-axis.
