Answer:
I think it's 3
Step-by-step explanation:
To calculate the gradient equals to
y(1)-y(2)
-----------
x(1)-x(2)
So - 5 - 1 = - 6
6 - 2 = 4
-6 - 3
--- = ----- x
4 2
And the first y intercept is 1 so I guess it's 3.
Just for refernece, not sure if I'm correct. Sry

Answer:
9x + x
Step-by-step explanation:
Answer: the box contained 9 square chocolates and 15 round chocolates.
Step-by-step explanation:
Let x represent the number of square chocolates contained in the box.
Let y represent the number of round chocolates contained in the box.
The box of chocolates contains square chocolates, which weigh 10g each and round chocolates which weigh 8g each. The combined weight of all the chocolates is 210g. It means that
10x + 8y = 210- - - - - - - - - - -1
The number of round chocolates is 3 less than twice the number of square chocolates. It means that
y = 2x - 3
Substituting y = 2x - 3 into equation 1, it becomes
10x + 8(2x - 3) = 210
10x + 16x - 24 = 210
26x = 210 + 24
26x = 234
x = 234/26
x = 9
y = 2x - 3 = 2 × 9 - 3
y = 18 - 3
y = 15
