The point P = {3, 19] lie5 fixed in place on the curve 3; = 1132 l D: + 7. Also an the curve is a variable paint Q = (1:, 1:2 + :E + 7), so the line 1312? is the secant line between peints P and Q. If :13 = 3.1, W} has a Slope equal to: l l and if :1: = 3.01, E has a Slope equal to: l l and if :13 = 2.9, W} has. a Slope equal to: l l and if I = 2.99, W} has. a alepe equal to: l ' Baaed en the above reaulta, estimate the slope of the tangent line tn the curve at P = (3, 19)
