Q. Find the slope of the tangent line to the graph of x=−6y2+9y−4 at (−1,1).
Find Derivative: First, we need to find the derivative of the function x=−6y2+9y−4 to find the slope of the tangent line at the point (−1,1). We'll use implicit differentiation, where we differentiate both sides of the equation with respect to y.
Substitute Value: Next, we substitute y=1 into the derivative to find the slope of the tangent line at that specific point.
Calculate Slope: Since the slope of the tangent line is the derivative evaluated at the point, the slope at (−1,1) is −3.
