In a linear programming problem, the constraints are:

constraint $1$: $5x_1+30x_{2}46$

constraint $2$: $15x_1+33x_{2}118$

What value from constraint $2$ can the slope of the objective function not exceed in order for the optimal solution point to remain optimal?

Another way to ask this is$,$ what's the slope of constraint $2?$

Round your solution to $2$ decimal places.
