Answer 1

A solution to a system of equations are where the two lines cross over each other.

System A the graph shows one line which means the two lines are on top of each other. This means any point on the lines are a solution so there are infinite number of solutions.

System B, the lines cross at one point is there is only one solution which is at (-3,2)

System C the two lines are parallel to each other and never cross so there are no solutions.

Answer 2

Step-by-step explanation:

(i) Infinite solution

If there is only one line then it is a infinite solution.

(ii) One solution

Both are intersecting each other.

Solving

-x - 1 = x + 5

-x - x = 5 + 1

-2x = 6

x = 6/-2

x = -3

y = -x + 5

y = -3 + 5

y = 2

(iii) No solution

Because they are parallel to each other
