How do you combine like terms?

Back

By adding or subtracting coefficients of terms that have the same variable raised to the same power.

Front

What is a linear equation?

Back

What does the slope of a line represent?

Back

The rate of change of y with respect to x, indicating how steep the line is.

Front

What is the y-intercept?

Back

The point where the line crosses the y-axis, represented by the value of y when x = 0.

Front

What is a function?

Back
