The video tutorial explains how to find the intersection point of a line and a circle in the first quadrant. It begins by analyzing the line's equation and the circle's properties, then sets up a system of equations. The tutorial demonstrates solving the system using substitution and the quadratic formula, focusing on the positive solution. Finally, it calculates the intersection point's coordinates, rounding them to three decimal places.

What is the equation of the line given in the problem?

• y = 2x + 1
