Can someone help plz

Find x & pleassse me !

Which steps could be part of the process in algebraically solving the system of equations, y+5x=x^2+10 and y=4x-10

Me i need ! find the asymptote and determine the end behavior of the function from the graph. the asymptote of the function is= blank 1 . for very high x-values, y =blank 2 options for blank 1 x=2 x=-2 x=3 x=-3 blank 2 options moves towards negative infinity moves toward the horizontal asymptote moves toward the vertical asymptote moves toward positive infinity
