One of the tables below contains (x,y) values that were generated by a linear function. Determine which table, and then write the equation of the linear function represented by the table

Table 1
x 2 5 8 11 14 17 20
y 1 3 7 13 21 31 43

Table 2
x 1 2 3 4 5 6 7
y 10 13 18 21 26 29 34

Table 3
x 2 4 6 8 10 12 14
y 1 6 11 16 21 26 31

I believe it's table 3
because the y values are constant
now I would chose 2 points and find the slope. then use the point-slope formula to find the equation$$\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }=m$$for slope and$$y-y _{1}=m(x-x _{1})$$ for point-slope
