What is a system of equations?

Back

A set of two or more equations with the same variables that are solved together.

Front

What does it mean if a system of equations has no real solution?

Back

It means that the lines represented by the equations are parallel and do not intersect.

Front

How can you determine if a graph represents a function?

Back

Use the vertical line test: if a vertical line intersects the graph at more than one point, it is not a function.

What is the slope-intercept form of a line?

Back

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of the y-value with respect to the x-value.

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input (x-value) has exactly one output (y-value).

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.

How do you find the equation of a line given a point and a slope?
