The video tutorial explains how to find the slope of a tangent line using implicit differentiation. It starts by setting up the problem and calculating the y-value when x equals 1. The process of implicit differentiation is demonstrated step-by-step, leading to solving for dy/dx. Finally, the slope of the tangent line is calculated by substituting the values of x and y into the derived expression.

What is the main goal of the video tutorial?

• To calculate the area under a curve

• To determine the maximum value of a function

• To find the slope of a tangent line at a specific point

• To solve a quadratic equation
