How do you Plot a Graph?

Answer 1

First you have to know what kind of equation you have. The most common is standard form and y-intercept form. The easiest to understand is y-intercept form(In my opinion).

Y-intercept form uses this formula: y=mx+b where m=slope and b=y-intercept.

So if you have y=2x+5, you would solve it like this:

First ou would plot the point (0,5) since the y-intercept is 5 which means x=0 and y=5.

Then from your point either go up two, right one....or go down two, left one and put the point down. Then draw a line through your points.

Some points that should fall on the line are (0,5), (1,7), (2,9), (-1, 3), (-2,1)

Answer

1. Locate the y-intercept on the graph and plot the point.
2. From this point, use the slope to find a second point and plot it.
3. Draw the line that connects the two points.

We can learn how to graph in online.In online we can also get the graph of equations.Learning graphing the equations is very easy, once if we know the procedure to graph the equations.There are many ways to learn is followed in online to draw the graph.In general the graph displays the nature of relationship between the variables. One of the most useful graph that we obtain quite often is the linear graph. All these ordered pairs (s, p) can be plotted as points in the Cartesian plane where its horizontal axis is the s-axis and the vertical axis is the p-axis. These points now define what is called the learn graph of the relation.

Linear equations graphing

• Let x and y be two variables. If they are connected by an equation of the form y = mx + c, then x and y are linearly related. the equation y = mx + c represents a straight line in the Cartesian plane. This is the reason why the relationship between x and y is called linear.
• For each value of x, the equation y = mx + c gives a value of y and ordered pair (x, y) of numbers can be obtained. The set of all such ordered pairs defines the graph of y = mx + c, called a learning linear graphing.
• In the equation y = mx + c, the number m is called the slope of the line and c is known as the y-intercept. The y-intercept is the value of y when x = 0. Sometimes the y-intercept c is 0. In this situation, the equations of the line is y = mx and we say that the line passes through the origin.
• The basic principle behind drawing a linear graph is that only two points are needed to graph a straight line.

Answer 2

Although you have not said so, the nature and level of the question suggests that you are talking about a linear equation in only 2-dimensional space.

The general form of a linear equation in 2-D is

ax + by + c = 0

If the equation is in the form y = mx + c, its general form is mx - y + c = 0,

that is, a = m, b = -1 and c remains unchanged.

Step 1: Cover up the y term. That leaves ax + c = 0 which gives x = -c/a.

Step 2: Mark the point P = (-c/a, 0) on the coordinate plane.

Step 3: Cover up the x term. That leaves by + c = 0 which gives y = -c/b. Step 4: Mark the point Q = (0, -c/b) on the coordinate plane.Step 5: Join up P and Q and extend in both directions.

DONE!

Answer 3

Take the function f(x)=x. The graph is linear.
