Question

What is y-1/2x=-1
and what is y=1/2x+4

Answer 1

No solutions

Explanation:

y - 1/2x = -1

y = 1/2x + 4

Move 1/2x over to other side for 2nd equation

y - 1/2x = 4

You can tell that if you plot the lines on a graph, there would be no intersecting points because the line is parallel, meaning there are no solutions.
