Well, the unit rate in the table is approximately 1.143 (8/7)
So, the only lines which have unit rate in between 1.143 and 2 are Line 3 (1.5) and Line 4 (1.2).
5x + 2 must be equal to 17. Subtract to from both sides, then divide both sides by 5 and x = 3. 3y - 6 must equal 21. Add 6 to both sides, then divide both sides by 3, and y = 9.
