Front

If you graph the system of equations, what is the solution among (-4, 1), (4, -1), (4, 5), (5, 4)?

Back

(-4, 1)

Front

Is the point (-1, -5) a solution to the system of equations y = -x + 2 and y = 3x - 2?

Back

No

Front

What is a system of equations?

Back

A set of two or more equations with the same variables.

Front

What does it mean for two lines to intersect?

Back

It means they have a common solution, or point, where they meet.

Front

How can you determine if a point is a solution to a system of equations?

Back

Substitute the point's coordinates into each equation; if both equations are satisfied, it is a solution.

Front

What is the graphical representation of a system of equations?

Back

It is the intersection point(s) of the lines representing the equations.

Front

What is the significance of the solution (x, y) in a system of equations?

Back

It represents the values of the variables that satisfy all equations in the system.
