Math Problem Statement

A system of equations is given as y = -2x - 3 and y = -2x + 2. How many solutions does this system have?

Solution

The system of equations in the image is:

y=2x3y = -2x - 3 y=2x+2y = -2x + 2

Step 1: Analyze the equations

Notice that both equations have the same slope of 2-2. This means that the two lines are parallel. When two lines are parallel, they never intersect.

Step 2: Identify the number of solutions

Since the lines are parallel and do not intersect, there is no solution to the system of equations. This is an example of an inconsistent system.


Final Answer:

The correct option to select from the drop-down menu is:

No solution\boxed{\text{No solution}}
