Front

Define a tangent line in relation to a curve.

Back

A tangent line is a straight line that touches a curve at a single point without crossing it.

Front

What is the relationship between the derivative and the slope of a tangent line?

Back

The derivative of a function at a point gives the slope of the tangent line at that point.

Front

How do you find the slope of a tangent line at a given point on a curve?

Back

Take the derivative of the function and evaluate it at the given point.

Front

What is the formula for the slope of a line?

Back

Slope (m) = (y2 - y1) / (x2 - x1) for two points (x1, y1) and (x2, y2).
