Find the slope of the line tangent to the graph of the function at the given value of x.

y = 9x^5/2 - 7x^3/2; x = 4

a. 159
b. 96
c. 6
d. 8

I am stuck what do I do to find the answer?

Please reply with clarification. For instance, your first term could mean "(9/2)x⁵" or "9x^5/2".

Note: To "find the answer", you need to find the value of the slope (the derivative) at the given x-value. Then find the y-value at that x-value, to find the point in question. Then use the slope and the point, together with whichever method and/or formula you learned back in algebra, to find the line equation.
