Step-by-step explanation:

Answer 2

Answer:

8)

$3x-3y=6\\-x+y=-2$

Consistent and Dependent

9)

$x+y=0\\-x+y=-8$

Consistent and Independent

10)

$x+y=0\\-x+y=-8$

Inconsistent

11 )  (0, 3)

12)  (-2, 1)

Step-by-step explanation:

Question 8

The slope-intercept equation of the line is:  y = x - 2

Therefore, the correct set of equations is:

$3x-3y=6\\-x+y=-2$

Consistent and Dependent, as:

• Same line
• Infinite solutions

Question 9

The slope-intercept equation of the lines are:

y = x - 8   and   y = -x

Therefore, the correct set of equations is:

$x+y=0\\-x+y=-8$

Consistent and Independent, as:

• Intersects at 1 point
• One solution

Question 10

The slope-intercept equation of the lines are:

y = -2x + 3  and  y = -2x + 1

Therefore, the correct set of equations is:

$4x+2y=6\\4y=-8x+4$

Inconsistent

• Parallel lines
• No solutions

Question 11

Solution is where the two lines intersect:

Solution (0, 3)

Question 12

Solution is where the two lines intersect:

Solution (-2, 1)
