Which of the following explains whether all of Francesca’s work is correct? Each step is correct because she plotted the point, drew a line to the x-axis to form a right triangle, used the Pythagorean theorem to find the hypotenuse, and finally wrote the correct ratios for all six functions. She made her first error in step 1 because she should have drawn the line to the y-axis to form the right triangle. She made her first error in step 2 because she should have used a negative value for r. She made her first error in step 3 because the sine, cosine, and tangent ratios are incorrect, which also results in incorrect cosecant, secant, and tangent functions.
