Substitute the values of x into the equation and see if they produce the same y values shown in the table.

Okay, for the first one, the table says when x is 0 y would be 8, lets substitute 0 for x and see if y becomes 8 in the equation.$$y=12(0)+8$$$$y=8$$See y is indeed equal to 8 when x is 0. Use this sample to do the rest.

It's pretty Easy.
First take the equation:
y = 12x + 8

Now let's substitute the "x" values from the table and if the corresponding "y" value comes in the end. That means the equation correctly represents the function for the data.

I won't give the Answer, as there would be no point in "studying" then. But i'll do one for you:

y = 12x + 8
(take the first 'x' value and substitute:
y = 12(0) + 8
y = 0 + 8
y = 8
(see, the table shows that if the value of 'x' is 0, the 'y' would be 8)

Do the same with the rest...
