Answer:
{x,y} = {37/11,-10/11}
Step-by-step explanation:
// Solve equation [2] for the variable y
[2] y = 3x - 11
// Plug this in for variable y in equation [1]
[1] 4x - 5•(3x-11) = 18
[1] -11x = -37
// Solve equation [1] for the variable x
[1] 11x = 37
[1] x = 37/11
// By now we know this much :
x = 37/11
y = 3x-11
// Use the x value to solve for y
y = 3(37/11)-11 = -10/11
Solution :
{x,y} = {37/11,-10/11}

51 I thinks that’s the correct answer
Part A:
Consider from x = -5 to x = -4, they are 1 unit apart and the difference of their outputs is given by:
-3 - (-11) = -3 + 11 = 8.
Thus, the value of the output increases by 8 units for each one unit increase in the input.
Part B:
Consider from x = -3 to x = -1, they are 2 units apart and the difference of their outputs is given by:
21 - 5 = 16.
Thus, the value of the output increases by 16 units for each two units increase in the input.
Part C:
Consider from x = 0 to x = 3, they are 3 units apart and the difference of their outputs is given by:
53 - 29 = 24.
Thus, the value of the output increases by 24 units for each three units increase in the input.
Part D:
It can be noticed that the ratio difference in the outputs to the input intervals are equal for all the given input intervals.
i.e 8 / 1 = 16 / 2 = 24 / 3.
