What is Meant by Graphing Linear Equations?
Graphing Linear Equations represents the graph of the given linear equation. As it always results in the form of a straight line. We generally use the graphical form of representation to prove the relationship between two or more quantities. The graph of the linear equations with two variables is a line.
One of the most important concepts of algebra is Graphing Linear Equations. To graph the equation, it should be in the form of y = mx + b, also known as the y-intercept form, where m is the slope of the equation.
Steps for Solving Graphical Linear Equations
Solving the linear equations graphically and represented in a coordinate plane is called graphical linear equations. The steps that should be followed to solve a linear equation using the graphical method are listed below:
- Firstly, ensure the given linear equation is in y-intercept form, ie., y = mx + b.
- Now, go with the trial and error method and find the value of (x,y) upto three pairs, which meet the linear equation.
- Calculate the x-intercept and y-intercept of the equation. Substitute the value of x=0 in the equation to find the y-intercept and its outcomes in x=a. For the sake of x-intercept, substitute the value of y=0 in the equation and result in y=c.
- As a result, the points are (a, 0) and (0, c). Now, put the value of x and y in a tabular form.
- In this step, you have to plot all the points on the graph.
- Now, it's time to join all the points and obtain the straight line representing the given linear equation graphically.
Examples of Graphing Linear Equations
Draw the linear equation of 2x+y=7 graphically?
Solution:
Given equation is 2x+y=7
Rearrange the given linear equation in the form of y = mx + b ie., y = -2x + 7
You can find two solutions, corresponding to the x-intercepts and y-intercepts of the graph, by setting the first x=0 and then y=0.
When x=0, we get:
y = -2(0) + 7
y = 7
When y=0, we get:
-2x+7=0
-2x = -7
-x = -7/2
x = 3.5
The coordinates of the plane are (0, 7), (3.5, 0) for the given linear equation 2x+y=7. The graphical representation of the linear equation is shown below.
FAQs on Graphing of Linear Equations Calculator
