Coordinates, gradient and tangent work (see image).

are my answers correct? -
a. p= (1.9,1.9) or (2,2) q=(2,3)
b. (rise over run) 3-1.9/2-1.9 = 11
and can anyone solve q. c -
c.

a)

b)

c)

Step-by-step explanation:

Given the curve

a) If the x-coordinate of P is , then the y-coordinate is so point P has coordinates

If the x-coordinate of Q is , then the y-coordinate is so point Q has coordinates

b) The gradient of the secant RQ is

c) If then the gradient

step-by-step explanation:

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
