Answer:
D) the lines coincide
Step-by-step explanation:
1. y = 4 - x
2. 2y = 8 - 2x
divide eq2 by 2:
y = 4 - x
eq 1 and 2 are identical
For a system of the equation to be a Dependent Consistent System, the system must have multiple solutions for which the lines of the equation must be coinciding. The correct option is D.
What is a System of equations?
Inconsistent System
For a system of equations to have no real solution, the lines of the equations must be parallel to each other.
Consistent System
1. Dependent Consistent System
For a system of the equation to be a Dependent Consistent System, the system must have multiple solutions for which the lines of the equation must be coinciding.
2. Independent Consistent System
For a system of the equation to be an Independent Consistent System, the system must have one unique solution for which the lines of the equation must intersect at a particular.
The graph of the given system of equations can be drawn as shown below therefore, It can be concluded that the lines coincide. Hence, the correct option is D.
