Question 483193
y = 2x + 3 
y = 2x + 5
You know by looking at these two problems that the slope is the same for each equation (y = mx + b - the slope is 2) and they have a different y-intercept.
---------------------------
 
First - what is the y-intercept for each of these equations? 
1st: 3
2nd: 5
-------------------

Second - can you say anything about this system of equations - visualize the solution?
The line are parallel.
They have no common point.
The system has no solution.
