What are the zeroes of a function?

Back

The zeroes of a function are the values of x for which the function f(x) = 0. They are the x-intercepts of the graph of the function.

What does it mean for a system of equations to have one solution?

Back

A system of equations has one solution when the equations represent lines that intersect at exactly one point.

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

Back

A system of equations has infinitely many solutions when the equations represent the same line, meaning every point on the line is a solution.

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

Back

To determine if a point (x, y) is a solution, substitute x and y into both equations. If both equations are true, then the point is a solution.
