We have the next linear equation y=5x+1
For the first row,
y=11
we substitute the value in the equation
11=5x+1
we clear x in order to know the value of x
5x=11-1
x=10/5
x=2
For the second row
x=4
we substitute the value in the equation
y=5(4)+1
y=20+1
y=21
For the third row
y=31
we substitute the value in the equation
31=5x+1
5x=31-1
5x=30
x=6
For the fourth row
x=8
we substitute the value in the equation
y=5(8)+1
y=40+1
y=41
The table of the equation

2 11
4 21
6 31
8 41
