It’s (4,5) because the slope is 1/1 meaning up one and right one. So when you graph up one and right one you get (4,5) To get the slope from y=x+1 you always look at what’s in front of x In this case it’s just x so there’s an imaginary 1 in front of it and for a slope it’s rise over run so it’s 1/1 Hope that’s easy to understand
