y = 6 – x and y = x – 2
(2, 4)
(–4, 2)
(4, 2)
no solutions

6.
y = 2x – 1 and y = x + 3 (1 point)(4, 7)
(7, 4)

(–7, –4)
infinite solutions







7.
y = 4x and y + x = 5

(–4, 1)
(1, 4)
(–3, 2)
(2, 3)

    #5: Bzzt
    plug in your values:
    2 = 6-(-4)
    -4 = 2-2
    How about (4,2)

    #6 Nope
    #7 Nope

    Post your work and we can show you where you went wrong. You're evidently not getting the method for solving these things. You might try reviewing your own materials first.
