Can someone please explain what i have to do.

(4,5)

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

Ithink you're supposed to multiply 12.50 which is how much he makes per hour and then multiply it by each number then add whats left togrther and there's your answer

(answer 2 )i’m very smart that’s how i know the answer.
