Answer:
(21, 5)
Step-by-step explanation:
y = -x
y = -(-7)
y = 7
The point is reflected, so it is equidistant on both sides of the reflection line. It takes 14 units to get to the reflection line, -7 + 14 = 7 (the reflection line).
So, another 14 on the other side would be 14 + 7 = 21

Answer/Step-by-step Explanation:
==>Given:
Ratio of cost of 1m polyester fabric to 1m of cotton fabric = 2:7
I.e. if 1m of polyester fabric = £2, then 1m of cotton fabric = £7.
==>Required:
a. Cost of polyester fabric for the following lengths:
i) 6m ii) 8m iii) 9m
Thus, having known that cost of 1m polyester fabric = £2, therefore,
i) 6m polyester fabric = 6×2 = £12
ii) 8m polyester fabric = 8×2 = £16
iii) 9m polyester fabric = 9×2 = £18
b. Cost 8 cotton fabric for the following lengths:
i) 2m ii) 6m iii) 8m iv) 9m
Thus, since 1m of cotton fabric = £7, therefore,
i) 2m cotton fabric = 2×7 = £14
ii) 6m cotton fabric = 6×7 = £42
iii) 8m cotton fabric = 8×7 = £56
iv) 9m cotton fabric = 9×7 = £63
The answer is 14 that's it
