Solving Systems of Equations with Slope Intercept Form

The video tutorial explains how to solve systems of equations by graphing, focusing on using a TI-84 Plus Silver Edition graphing calculator. It covers the basics of systems of equations, demonstrates graphing techniques, and provides step-by-step instructions for finding intersections. The tutorial also addresses common errors and how to adjust settings to view intersections correctly. The video concludes with a summary of the graphing process and encourages viewers to practice solving systems independently.

What is a system of equations?

• A single equation with one variable

• A single equation with multiple variables

• At least two equations with the same variables

• Two equations with different variables

Which of the following is NOT a method for solving systems of equations?

• Integration

• Elimination

• Graphing

• Substitution

What is the solution to a system of equations represented by on a graph?

• The midpoint of the two lines

• The point where one line crosses the y-axis

• The point where one line crosses the x-axis

• The point where the two lines intersect

What is the first step in graphing a system of equations using a TI-84 Plus calculator?

• Press the trace key

• Press the zoom key

• Press the graph key

• Enter the equations into the function editor

Which key do you press to access the function editor on a TI-84 Plus calculator?

• Y=

• Zoom

• Trace

• Graph

What is the intersection point of the equations y = 5x - 1 and y = 3x + 12?

• (0, 0)

• (2, 7)

• (-1, -5)

• (6.5, 31.5)

What should you do if you get an error message while finding the intersection?

• Restart the calculator

• Change the window settings

• Re-enter the equations

• Press the graph key again

What does the 'Zoom Standard' setting do on a TI-84 Plus calculator?

• Zooms out on the graph

• Adjusts the window settings

• Zooms in on the graph

• Resets to a standard view screen

If the intersection is outside the view screen, what should you adjust?

• Xmin and Xmax values

• Ymin and Ymax values

• Zoom settings

• Graph settings

What is the final step in finding the intersection on a TI-84 Plus calculator?

• Press the trace key

• Press enter three times

• Press the zoom key

• Press the graph key
