We are currently interpreting derivatives using the delta process in my analytical geometry class. The problem is: Calculate the coordinates (x,y) of the point at which the graph y= 0.027x^2 + 8.3x -7.5 is at a 35 degree angle from the horizontal. I have figured the derivative to be equal to 0.054x + 0.027 delta x +8.3(adsbygoogle = window.adsbygoogle || []).push({});

Question #1: Is the derivative correct?

Question #2: What do I do now?

Thanks
