Answer:
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 
A. (−3, 3)
<span>3x – 4y = 21
</span>3(-3) - 4(3) = 21
-21 = 21 >>>>> not equal
B. (−1, −6)
<span>3(-1) - 4(-6) = 21
</span>21 = 21 >>>>>>>>>>Equal
C. (7, 0)
<span>3(7) - 4(0) = 21
</span>21 = 21>>>>>>>>>>equal
D. (11, 3)
<span>3(11) - 4(3) = 21
</span>21 = 21 >>>>>>>>>equal
