Front

What is a proportional relationship?

Back

A relationship where the slope is a constant rate of change, and the initial value is zero.

Front

What is the initial value in a linear equation?

Back

The starting point for the equation, also called the y-intercept.

Front

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

Back

The equation of a linear relationship in the form of y - y1 = m(x - x1).

Front

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

Back

The equation of a linear relationship in the form of y = mx + b.

Front

What characterizes a linear relationship?

Back

A relationship that can be expressed in y = mx + b and shows a straight line when graphed due to a constant rate of change.

Front

What does 'slope' represent in a linear equation?

Back

The rate of change of the relationship, indicating how much y changes for a unit change in x.

Front

What is the difference between proportional and non-proportional relationships?

Back

Proportional relationships have a constant rate of change and pass through the origin, while non-proportional relationships do not.

Front

What is the x-intercept?

Back

The point where the graph of an equation crosses the x-axis, meaning y = 0.

Front

What does 'rate of change' refer to?

Back

The ratio that describes how much one quantity changes in relation to another quantity.

Front

What is the Standard Form of a linear equation?

Back

The equation of a linear relationship in the form Ax + By = C, where A, B, and C are integers.
