POSTTest: Linear Relationships

Front

What is the y-intercept in the equation y=mx+b?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of b in the equation.

Front

What does the slope (m) represent in the equation y=mx+b?

Back

The slope (m) represents the rate of change of y with respect to x, indicating how steep the line is.

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

How do you find the x-intercept of a linear equation?

Back

To find the x-intercept, set y=0 in the equation and solve for x.

Front

What is the Standard Form of a linear equation?

Back

The Standard Form is Ax + By = C, where A, B, and C are integers.

Front

What does a positive slope indicate about a linear function?

Back

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

Front

What does a negative slope indicate about a linear function?

Back

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

Front

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

Back

The Point-Slope Form is y - y1 = m(x - x1), where (x1, y1) is a point on the line.

Front

How can you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope (m) but different y-intercepts (b).

Front

How can you determine if two lines are perpendicular?

Back

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