Fill in the blanks

y = 10x + 100
x y
-20 ?
-10 ?
0 ?
10 ?

I don't see any blanks to fill in. Are they telling you values of y and asking you co compute x? Or vice versa?

The spacing changed the format I had. the values for x are -20, -10, 0, 10 now I need to find the values for Y which is why I put the ? smybol.

If x = -20,
y = 10x + 100 = -200 + 100 = -100

If x = 0,
10x + 100 = 100

For every 10 added to x, y increases by 100.

If x = -10,

y = 10x + 100 = -100 + 100 = 0

If x = 10,
y = 10x + 100 = 100 + 100 = 200

So, the missing values for y are -100, 0, 100, 200 respectively.
