y = = x + [? ]
Enter the answer that
belongs in [?].

Answer 1

y = x + (-5)

Explanation:

The equation appears to be linear, which means we can find the change in x by either:

Plugging in any corresponding x and y values and solving

Using the slope formula and solving for b from the equation y = mx + b

I'll demonstrate the first method since the y-intercept is what we need to find

First method: We can use 1 and -4 as our x and y coordinate and we can let b represent the unknown value:

`-4=1+n\\-5=n\\y=x+(-5)`
