Answer:

[tex]\boxed{Y=2X+4}\\[/tex]

Step-by-step explanation:

[tex]\begin{array}{|c|ccc|c|}X&Y&Y-6&\dfrac{Y-6}{2}&\dfrac{Y-6}{2}+1 \\---&---&---&---&---\\1&6&0&0&1\\2&8&2&1&2\\3&10&4&2&3\\4&12&6&3&4\\5&14&8&4&5\\---&---&---&---&---\\\end {array} \\\\\\X=\dfrac{Y-6}{2}+1 \\X-1=\dfrac{Y-6}{2}\\2*(X-1)=Y-6\\2X-2+6=Y\\\\\boxed{Y=2X+4}\\[/tex]
