How is the equation y=2x similar to the equation y=2x+3 in the equation problem? How is it different?

Step-by-step explanation:

Both equations have straight line graphs. These lines have the same slope, 2. The first graph goes through the origin, so we say the y-intercept is (0, 0). The second graph is parallel to the first, but goes through (0, 3).

These two graphs never intersect, and thus if we regard them as representing a system of linear equations, we conclude that the system has no solution.
