For it to be a linear equation, the same difference in x must produce the same difference in y always.
Choice A.
difference in x: 2 - 1 = 1
difference in y: -6 - (-2) = -4
difference in x: 3 - 2 = 1
difference in y: -2 - (-6) = 4
A difference of 1 in x gave a difference of -4 in y and another difference of 1 in x gave a difference of 4 in y.
This is not linear.
Choice B.
difference in x: 2 - 1 = 1
difference in y: -5 - (-2) = -3
difference in x: 3 - 2 = 1
difference in y: -9 - (-5) = -4
A difference of 1 in x gave a difference of -3 in y and another difference of 1 in x gave a difference of -4 in y.
This is not linear.
Choice C.
difference in x: 2 - 1 = 1
difference in y: -10 - (-2) = -8
difference in x: 3 - 2 = 1
difference in y: -18 - (-10) = -8
Do the other differences. All differences in y are -8 corresponding to a difference in x of -1.
This is linear.
Choice D.
The differences in y vary. It is not linear.
Answer: Choice C is linear.

Answer:
perimeter = 2*a = 2*54 mm = 108 mm
Step-by-step explanation:
For any geometrical figure, the perimeter is the sum of all his sides.
In a rectangle figure, have four sides, two of them equals: a (upper side), b (lateral side), so the perimeter will be:
perimeter = a+a+b+b = 2*(a+b)
A square is a particular case of rectangle figure, in which: a = b.
So, for a square:
perimeter = 2*(a+a) = 2*(2a) = 4*a
I think it’s 6 cups of chocolate chips.
Explanation:
If in the first batch the ratio of 2 is 4 cups, that means that the ratio 1 would be 2 cups. In the second batch, the chocolate chip ratio was 3, so it would be 6 cups. I hope this helps!!!
