Answer:

4x+5y= -12

subtract 4x from both sides

5y = -4x - 12

divide by 5

y = -4/5 x - 12/5

-2x+3y= -18

subtract -2x

3y= -2x - 18

divide by 3

y= -2/3x -6

Option 1: $y = 5x+5$ is the correct answer

Step-by-step explanation:

We can put the values of x in each option one by one and then compare the output to find the best option

So,

Putting x=1,2,3,4,5...

$y = 5(0)+5 = 0+5 = 5\\y = 5(1) +5 = 5+5 = 10\\y = 5(2) + 5 = 10+5 = 15\\y = 5(3) + 5 = 15+5 = 20$

The values of x in the function are producing the output values of y, which means that the function for values given in the table is defined by: y= 5x+5

Hence,

Option 1: $y = 5x+5$ is the correct answer
