What is the Y-Intercept?

Back

The Y-Intercept is the point where a line crosses the y-axis.

Front

What is the X-Intercept?

Back

The X-Intercept is the point where a line crosses the x-axis.

Front

What form is represented by the equation Ax + By = C?

Back

This equation is in Standard form.

Front

What is the Point-Slope form of a linear equation?

Back

The Point-Slope form is given by y - y1 = m(x - x1), where m is the slope.

Front

What is the Vertical Line Test?

Back

The Vertical Line Test is a method to determine if a graph represents a function; if a vertical line crosses the graph more than once, it is not a function.

Front

What does the slope of a line represent?

Back

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

Front

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the Slope-Intercept form of a linear equation?

Back

The Slope-Intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate about a line?

Back

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