We can find the y coordinate where the normal line intersects the curve by substituting 4 for x into the equation for the normal line:

#4(4)+y = 22#

#y = 6#

Substitute the point #(4,6)# into the equation for the curve:

#6 = asqrt4+bsqrt4#

#6 = 2a+2b#

#a+b = 3#

Without more information, we can say no more about the values of a and b.
