    Answer:

    (3,7)

    Step-by-step explanation:

    Use a system of equations to solve for x and y which would be the only points where the two lines intersect

    x+y=10

    y=2x+1

    since y=2x+1 you can put 2x+1 for y

    so x+2x+1=10

    3x+1=10

    3x=9

    x=3

    put that back into x+y=10

    3+y=10

    y=7

    So the only point where those two lines intersect is (3,7)

    Hope that helps 🙂
