Which graph shows a linear function the first one A second one on top right B the bottom left c and bottom right D

Part A: If 3 is equal to x, we can substitute it into the equation. The equation would look like this: 4(3)-1 ≤ 11

We can simplify the equation using multiplication: 12-1≤11

Now, we do subtraction: 11≤11

This is true because ≤ means less than or equal to. If we substituted ≤ for <, it would no longer be true because 11 is not less than 11.

Part B: We need to substitute every number in. I will go top to bottom until we determine our answer. 8*8=64, so it cannot be 8 because 64+1≠57

8*7=56. Now, we add 1 to 56 and we get this: 57=57

This is true because they are the same number, therefore equal.

The value "7" would make the equation true.
