When the lines are parallel then there is no solution to the system of equations.
This happens because the intersection is the solution. And when there is no intersection then there is no solution.
Here's another one.
See the attached picture.
3 is the remainder because the closest is 7 times 21 so it’s remainder 3
Quotient is the correct answer
All real numbers greater than or equal to -8. You can see 3 is a minimum point because at 3 the numbers start to increase again. -8 is the lowest number and the function is increasing as x approaches infinity starting at 3.
