Answer:
A) y=2x+6
2y=4x+12
Step-by-step explanation:
The system of equations that has infinite solutions will have the same slope and same y-intercept.
Option A
The system is :
y=2x+6
2y=4x+12
When we divide through the second equation by 2, we get:
y=2x+6
y=2x+6
The two equations have the same slope and y-intercept.
Therefore the first system has infinite number of solutions.
For options B through D, the slope and y-intercepts are not the same.
Therefore the correct choice is A)
