# estimate the slope of the tangeant line to the curve at P(9,7)

The point P(9,7) lies on the curve y= √x +4. Let Q be the point (x,√x+4)
if x is 9.1, the slope of PQ is 0.166206
if x= 9.01, the slope of PQ is 0.16662
if x= 8.9, the slope of PQ is 0.1671323
if x= 8.99, the slope of PQ is 0.166713
Based on the above results, estimate the slope of the tangeant line to the curve at p(9,7)
