Answer:
y=x+43
Explanation:
Let the missing number = c
So we have the equation:
[tex]y=x+c[/tex]When x=5, y=48
[tex]\begin{gathered} 48=5+c \\ c=48-5 \\ c=43 \end{gathered}[/tex]Similarly, just to be sure:
When x=8, y=51
[tex]\begin{gathered} 51=8+c \\ c=51-8 \\ c=43 \end{gathered}[/tex]Therefore, the linear equation that gives the rule for the table is:
[tex]y=x+43[/tex]
