The discussion focuses on finding points on the ellipse defined by the equation x²/9 + y²/16 = 1 where the slope of the tangent equals 1. The derivative of the ellipse is given as dy/dx = -16x/9y. Participants suggest using implicit differentiation and substituting values to solve the equations -16x/9y = 1 and x²/9 + y²/16 = 1. The final solutions are identified as the points (4.5, -3.2) and (-4.5, 3.2), confirming that there are two points where the tangent slope equals 1.
