For the first picture, we can see that as the multiplier of x gets larger (1/2 vs 1 vs 2), the line gets steeper
Next, we can see that as more stuff is added to x, the higher it goes. For example, y=x+2 is higher than y=x for all values of x
Lastly, we can see that multiplying x by a negative number can completely shift the positioning of the line, as seen by comparing y=-x to y=x
