Answer:
7
Step-by-step explanation:
Let the missing value of y in the table be a.
Since, the slope of the line through the ordered pairs (1, 3), (2, a) is 4.
[tex] slope = \frac{a - 3}{2 - 1} \\ \\ 4 = \frac{a - 3}{1} \\ \\ 4 = a - 3 \\ \\ 4 + 3 = a \\ \\ a = 7[/tex]
Thus, the missing value of y in the table is 7
