Poorly shown. Is u a function of x? Is the symbol, "x", intended as a multiplication operation ? Write properly what you are actually given. What is the inequality statement shown? Why is it included? It is already self-evident and is unneeded.

"Gradient"? You'll need to straighten your equation some. You show u as a function of what looks to be x. This should be simplified, ASSUMING THAT x IS A VARIABLE AND NOT A MULTIPLICATION SYMBOL.

u=64.9x11-660
u=%2864.9%29%2811%29x-660-----(understand reason for this step?)
u=713.9x-660
The SLOPE is 713.9.
Do you understand why?
