Answer: 1. b

2. a

3. c

Explanation:

We will change the second equation to y form, then we get:

2x - y = - 6

- y = -2x - 6

y = 2x + 6

Then we plug in each point to see whether it fixes the equations.

a) 1. y = 3x + 8

4 ?= 3(-1) + 8

4 ?= -3 + 8

4 x 5

a) 2. y = 2x + 6

4 ?= 2(-1) + 6

4 ?= -2 + 6

4 = 4

Point a is a solution of the second equation, but not a solution for the first equation.

b) 1. y = 3x + 8

14 ?= 3(2) + 8

14 ?= 6 + 8

14 = 14

b) 2. y = 2x + 6

14 ?= 2(2) + 6

14 ?= 4 + 6

14 x 10

Point b only fits the first equation, but does not fix (not a solution) of the second equation.

c) 1. y = 3x + 8

2 ?= 3(-2) + 8

2 ?= -6 + 8

2 = 2

c) 2. y = 2x + 6

2 ?= 2(-2) + 6

2 ?= - 4 + 6

2 = 2

Point c fits both the first equations and the second equations.
