CPM Homework Help : APCALC Problem 10-9

Multiple Choice: The equation of the line tangent to the curve $3x^2y - 2x = y^2$ at the point $(1, 1)$ is:

Step 1:

$6xy+3x^2y^\prime-2=2yy^\prime$

Step 2:

$6(1)(1)+3(1)^2y^\prime-2=2(1)y^\prime$

Step 3:

Solve for $y^\prime$ . This is the slope of the line.
