Answer:
Explanation:
If you are given two lines and they have the same y intercept and the same slope and you graph them, you will find that they will be one on top of the other thus appearing to be 1 line. Any number will a solution for this condition.
For example,
y = 5x + 8
2y = 10x + 16
The y intercept occurs when x = 0
So both equations give a y intercept of 8
Every value of x that you can think of will give the same y in both equations. Hence there are infinitely many solutions
The x incept occurs when y = 0
x = -8/5 = -1 3/5 or 1.6
