y=mx + b b represents the y intercept so we can substitute it with 2. y = mx + 2 the point we are given, (1,1) is really just an x and y value. We can also substitute this into the equation. y = x + 2
Now that we have some type of equation, we can convert it to the form shown in the answer choices by subtracting y from both sides. 0 = x - y + 2 Hope this helps!
