What is the graph of the equation y = -x + 2?

Back

The graph is a straight line with a negative slope that crosses the y-axis at (0, 2) and the x-axis at (2, 0).

What is a function?

Back

A function is a relation where each input has exactly one output.

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis.

Front

What does it mean if a graph does not represent a function?

Back

It means that there are inputs (x-values) that correspond to multiple outputs (y-values).

Front

What is the 'magic number' in problem-solving?

Back

The magic number is the number you must circle that you know to pass.

How do you determine if a relation is a function using the vertical line test?

Back

If a vertical line intersects the graph at more than one point, the relation is not a function.

Front

What is the slope of a line?

Back

The slope is a measure of the steepness of the line, calculated as the rise over run.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases.

Front

What is the x-intercept of a line?

Back

The x-intercept is the point where the line crosses the x-axis.

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers.
