ImplicitDiff12: Problem 3 Previous Problem Problem List Next Problem (1 point) Regarding y as the independent variable and a as the dependent variable, find the slope of the tangent line, i.e. find dx/dy since y is the indedendent variable in this case, to the curve 2y + 5ry2 + 3yz - by = 285 at the point (3, 1). The slope of the tangent line to the curve at the point (3, 1) is
