Answer to Problem 22E
The system of equations of parallel lines (i.e. having same value of slope) will have no solution.
Explanation of Solution
Given information:
There is no solution to the system.
Calculation:
If the lines are parallel to each other i.e. they have same value of slope. Then the system of equations for these lines will have no solution. Example:
b.
To explain: that system of equation for the given situation if you are using elimination method.
b.

Answer to Problem 22E
The system of an equation has infinitely many solutions when the lines are coincident, and they have the same y-intercept.
Explanation of Solution
Given information:
The system has infinite number of solutions.
Calculation:
If the two lines have the same y-intercept and the slope, they are actually the same exact line. When the two lines are the same line, then the system should have infinite solutions. Example:
