a. Verify that the given point lies on the curve. b. Determine an equation of the line tangent to the curve at the given point. 4x2 + 2xy + 5y2 = 99; (3,3) SAY Q q X > m k -'G a. How do you know that the point is on the given curve? The point (3.3) is in the rst quadrant. The value of 4x2 + 2xy + 5y2 is 99 when x is 3 and y is 3. The value of 4x2 + 2xy + 5y2 is less than 99 when x is 3 and y is 3. The point (3,3) is in the domain of the implicit function. h. Write the equation for the tangent line in slope-intercept form. v=|E| (Use integers or fractions for any numbers in the equation.)
