Algebraic linear equations are mathematical functions that, when graphed on a Cartesian coordinate plane, produce x and y values in the pattern of a straight line. The standard form of the linear equation can be derived from the graph or from given values. Linear equations are fundamental to algebra, and thus fundamental to all higher mathematics.
Do you get confused when you have to write linear equations? Don't worry, that's about to change! In the previous unit, Graphing Equations you learned how to graph linear equations on a coordinate grid. In this unit, we are going to reverse that process and write equations to match a graph or a word problem. This unit is very important, because in many real life situations, you will not be.
Standard Form of a Linear Equation We will commonly see lines expressed in the standard form of a linear equation, especially when we look at and write systems of linear equations. The standard form of a linear equation puts the x and y terms on the left hand side of the equation, and makes the coefficient of the x-term positive.
Equation of a Line from 2 Points. First, let's see it in action. Here are two points (you can drag them) and the equation of the line through them. Explanations follow. The Points. We use Cartesian Coordinates to mark a point on a graph by how far along and how far up it is: Example: The point (12,5) is 12 units along, and 5 units up Steps.
Equations that are written in slope intercept form are the easiest to graph and easiest to write given the proper information. All you need to know is the slope (rate) and the y-intercept. Continue reading for a couple of examples! Example 1: Writing an Equation Given the Slope and Y-Intercept.Learn More
Recall that in Linear Functions, we wrote the equation for a linear function from a graph. Now we can extend what we know about graphing linear functions to analyze graphs a little more closely. Begin by taking a look at Figure 8. We can see right away that the graph crosses the y-axis at the point (0, 4) so this is the y-intercept.Learn More
Defining a Linear Equation. This lesson is on what a linear equation is. And the answer to that question is essentially a linear equation is any pattern of numbers that is increasing or decreasing.Learn More
The number of equations and the number of unknowns should be equal, and the equation should be linear (and linear independent). Then you can be expected that the equations have one solution. It is not necessary to write equations in the basic form. The calculator easily performs equivalent operations on the given linear system.Learn More
Writing linear equations using the slope-intercept form An equation in the slope-intercept form is written as Where m is the slope of the line and b is the y-intercept. You can use this equation to write an equation if you know the slope and the y-intercept.Learn More
System of linear equations can arise naturally from many real life examples. Generally speaking, those problems come up when there are two unknowns or variables to solve. In the figure above, there are two variables to solve and they are x and y.Learn More
