Front

What does 'b' represent in the equation y=mx+b?

Back

'b' represents the y-intercept of the line.

Front

What can be said about the slopes of parallel lines?

Back

The slopes of parallel lines are identical.

Front

What is the formula for the slope of a line?

Back

Slope (m) = (change in y) / (change in x) or rise/run.

Front

What is the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis.

Front

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

Back

Set y to 0 and solve for x.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises from left to right.

Front

What does a negative slope indicate about a line?
