Find an equation of the line tangent to the curve at the given point. 3 2 + 3x y = 140; (1,5) The equation of the line tangent to the curve isa. Verify that the given point lies on the curve. b. Determine an equation of the line tangent to the curve at the given point. x" + xy + 5y- = 11; (2,1) a. How do you know that the point is on the given curve? O A. The value of x + xy + 5y- is less than 11 when x is 2 and y is 1. O B. The point (2,1) is in the domain of the implicit function. O C. The point (2,1) is in the first quadrant. D. The value of x2 + xy + 5y is 11 when x is 2 and y is 1. b. Write the equation for the tangent line in slope-intercept form. y= (Use integers or fractions for any numbers in the equation.)
