How do you use a graph to find the solution of an equation?

To solve an equation graphically, draw the graph for each side, member, of the equation and see where the curves cross, are equal. The x values of these points, are the solutions to the equation.

How do you find the solution of a line on two graphs?

To solve a system of linear equations by graphing

1. Graph the first equation.
2. Graph the second equation on the same rectangular coordinate system.
3. Determine whether the lines intersect, are parallel, or are the same line.
4. Identify the solution to the system.
5. Check the solution in both equations.

Which type’s of equation can have infinite solutions?

linear equations
A system of linear equations has infinite solutions when the graphs are the exact same line.

How do you do graphs in math?

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.

How do you solve systems by substitution?

Solve a system of equations by substitution

1. Solve one of the equations for either variable.
2. Substitute the expression from Step 1 into the other equation.
3. Solve the resulting equation.
4. Substitute the solution in Step 3 into one of the original equations to find the other variable.
5. Write the solution as an ordered pair.

How do you solve a system of equations with infinite solutions?

Conditions for Infinite Solution If the two lines have the same y-intercept and the slope, they are actually in the same exact line. In other words, when the two lines are the same line, then the system should have infinite solutions.

How do you make a scatter graph?

Steps to create excel scatter plots: Select all the cells that contain data. Click on Insert tab. Look for Charts group. Under Chart group, you will find Scatter (X, Y) Chart. Click the arrow to see the different types of scatter and bubble charts.

How do you find the equation of a graph?

A linear equation produces a line graph. The equation takes the form y = mx + b, where m is the slope and b is the y intercept.

How do you graph x y coordinates?

Graphing X Y Coordinates. The X coordinate is generally plotted on horizontal axis. The Y coordinate is generally plotted on vertical axis. Both of the X and Y values are points of the coordinates. Here is a simple example, lets graph (3, 2) coordinate on a graph sheet. Select 3 on the x axis & then 2 on the y axis.

How do you draw a graph?

How to Draw a Graph. You may draw arrows on the ends of the line to indicate it is a number line that continues past your data sample. Put the label “X” to the right of the line to indicate the x axis. Mark the center of the line with a vertical tick mark and label it 0. This is the origin of the graph.
