Answer:
Y = 2x + 7
Step by step:
With x = 0 and y = 7, you can complete half the equation, y = ?x + 7
Then for the other values in the table, find the relation between x and y, subtracting 7 from y.
x = 2, y = 11-7
x = 3, y = 13-7
Y is double the value of x, so the equation can be completed now as y = 2x + 7
