Front

What is the geometrical representation of a linear equation?

Back

Straight line

Front

Which equation is written in STANDARD form?

Back

Front

In slope intercept form (y=mx+b), what does 'm' represent?

Back

The slope (rate of change)

Front

What is a pair of linear equations in two variables?

Back

A set of two linear equations in the same two variables

Front

What is the definition of a variable?

Back

The letter used to represent a quantity

Front

What is the general form of a linear equation in two variables?

Back

Ax + By + C = 0, where A, B, and C are constants.

Front

What does the slope of a line indicate?

Back

The rate of change of y with respect to x.

Front

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

Back

The value of y when x = 0.

Front

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

Back

Set y = 0 and solve for x.

Front

What is the difference between dependent and independent variables?

Back

Independent variable is manipulated, dependent variable is measured.
