How to Write an Equation for Each Vertical Tangent to the Curve?

Most tangents to curves have equations that follow the format of "y = mx + c." In these equations, "m" represents the tangent's slope, and "c" represents its intersection with the y-axis. Vertical ... Read More »

How to Write the Equation of a Tangent Knowing a Point?

How to Find an Equation of the Tangent Line to the Graph of F at the Indicated Point?

The derivative of a function gives the instantaneous rate of change for a given point. Think of the way the velocity of a car is always changing as it accelerates and decelerates. Although you can ... Read More »

How to Convert a Slope-Intercept Form Equation Into a General Linear Equation?

When writing linear equations, you can use either the slope-intercept form or general form. The advantage of slope-intercept form, or y = mx + b, is that you can immediately see the slope, m, and t... Read More »
