Question

What is the soultion for y=1/2x-4 and y = 1/2x+5

Answer 1

In the system:

`\begin{gathered} y=(1)/(2)x-4 \\ y=(1)/(2)x+5 \end{gathered}`

Both lines have the same slope, this means that they are parallel. The solution for a system of equations is the point were these two lines meet. But when 2 lines are parallel, they don't meet (never). This means that this system has no solution.
