Front

What does it mean for a system of equations to have infinite solutions?

Back

It means the lines representing the equations are the same line, thus intersecting at every point on the line.

What is the significance of the x-axis and y-axis in a graph of a system of equations?

Back

The x-axis typically represents the independent variable, while the y-axis represents the dependent variable.

What is the graphical representation of the equation y = 2x + 1?

Back

A straight line with a slope of 2 and a y-intercept of 1.

Front

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

Back

By substituting the point's coordinates into each equation to see if they hold true.
