Question
Which is TRUE about an inconsistent system?
- The y-intercepts are equal.
- The slopes are not equal.
- The lines are parallel.
- It has an infinite number of solutions.
Solution
An inconsistent system is one in which the equations cannot all be satisfied at the same time. This usually means that the lines represented by the equations do not intersect at a common point.
Let's go through the options:
-
"The y-intercepts are equal." - This is not necessarily true. An inconsistent system can have lines with different y-intercepts.
-
"The slopes are not equal." - This is also not necessarily true. An inconsistent system can have lines with the same slope.
-
"The lines are parallel." - This is often true for an inconsistent system. If the lines are parallel, they will never intersect, and the system is inconsistent. However, it's not the only way a system can be inconsistent. For example, three lines can form a triangle and still be inconsistent.
-
"It has an infinite solutions." - This is false. An inconsistent system has no solutions, not an infinite number of solutions.
So, the most accurate statement is "The lines are parallel." However, keep in mind that this is not the only way a system can be inconsistent.
