# Which system of equations is represented by the graph

## How do you determine which system is represented by a graph?

## What does the solution to a system of equations represent graphically?

Key Points

The solution to a system of linear equations in two variables is any ordered pair (x,y) that satisfies each equation independently. Graphically, solutions are **points at which the lines intersect**.

## How do you find a solution to a system of equations?

To solve a system of equations by graphing, graph all the equations in the system.

**The point(s) at which all the lines intersect are the solutions to the system**. Graph of System Since the two lines intersect at the point (1, 1), this point is a solution to the system.## How do you tell if a system of equations has no solution on a graph?

When you graph the equations, both equations represent the same line. If a system has no solution, it is said

**to be inconsistent**. The graphs of the lines do not intersect, so the graphs are parallel and there is no solution.## How do you graph systems?

## How do you graph equations?

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.## Which system of equation has no solution?

inconsistent system of equations

**An inconsistent system of equations**is a system of equations with no solution.

## Which systems of equations have no solution?

A system of linear equations has no solution when the graphs

**are parallel**.## How does the graph of a system of equations with one solution differ from the graph of a system of equations with infinitely many solutions or no solution?

The graph of a system with one solution is two intersecting lines. The graph of system with no solutions is two parallel lines. The graph of a system with infinite many solutions is a

**single**line.## What is the graph of the system of linear equation?

The graph of a linear equation is

**a line**. Each point on the line is a solution to the equation. For a system of two equations, we will graph two lines. Then we can see all the points that are solutions to each equation.## What system of linear equations have a graphs that coincides with each other?

consistent system

**A consistent system**is considered to be a dependent system if the equations have the same slope and the same y-intercepts. In other words, the lines coincide so the equations represent the same line.

## How many solutions are there of the graph is coinciding?

If the graph lines for equations coincide there are

**infinitely many solutions**.## What is the graph of system of linear equations in two variables?

To graph a linear equation by plotting points, you need to find three points whose coordinates are solutions to the equation. You can use the x- and y- intercepts as two of your three points. Find the intercepts, and then find a third point to ensure accuracy. Make sure the points line up—then draw the line.

## How do you identify a system of linear equations?

**There are three types of systems of linear equations in two variables, and three types of solutions.**

- An independent system has exactly one solution pair (x,y). The point where the two lines intersect is the only solution.
- An inconsistent system has no solution. …
- A dependent system has infinitely many solutions.

## How many solutions exist for the system of equations in the graph?

Each shows two lines that make up a system of equations. If the graphs of the equations intersect, then there is

**one solution**that is true for both equations. If the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations.## How many solutions does the system of linear equations represented in the graph below have?

There

**are an infinite number of solutions**. If you have a system of linear equations, the solution for the system is the value that makes all of the equations true. For two variables and two equations, this is the point where the two graphs intersect.## What are two linear equations with the same graph called?

Equivalent equations have the property that one equation can be made into the other equation by algebraic manipulation. For instance, consider our earlier example of x + 2 = 6 and 2x = 8.
