1. y = x + 6
y = 2x (1 point)
(6, 12)
(–12, –6)
(–6, –12)
(2, 4)
2. 3x + 2y = 7
–3x + 11 = y (1 point)
(6, –3)
(6, –7)
(5, –4)
3. 2x – y = –7
4x – y = –4
(–1.5, 4)
(1.5, 10)
(4, –1.5)
(–1.5, –2)
For questions 4–5, how many solutions does the system have?
4. –4y + 4 = x
2x + 8y = 8
one solution
two solutions
infinitely many solutions
no solution
5. 6x + 2 = y
3y – 18x = 12
one solution
two solutions
infinitely many solutions
no solution
