20 points Freya is collecting 50p and £1 coins. When she has 18 coins the value of them is £13. Let x be the number of 50p coins and y the number of £1 coins. Write a pair of simultaneous equations for this.

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
