Partial derivatives:
Lagrange multiplier:
4 equations:
By solving:
Second mathod:
Solve for x^2+y^2 = 7, x^3+y^3=10 first:
The maximum is 4
B has the equation -2 + 7 = -5
C has the equation -7 + 5 = -2
D has the equation 5 + (-7) = -2
Formula for slope:
y₂: 6
y₁: 8
x₂: 1
x₁: -2
Plug them into the slope equation:
-->
--->
The slope is .
