Answer:
Infinite solutions Answer explained below
Step-by-step explanation:
Let us see the various conditions for intersections of two lines in simplest way.
1. Same slope and same y intercept : Infinite solutions
2. Same slope and different y intercepts : No solution
3. Different slope and same y intercept : unique solution
4. Different slope and different y intercept : Unique solution
Here slope means the tangent of the angle line makes with the positive x axis and y intercept is the y coordinate at which the line intersect the y axis.
In our equations , we our slopes and y intercepts as
y=-3x+6
slope = -3 and y intercept = 6
y=6-3x
slope = -3 and y intercept = 6
Hence same slope and same y intercept , thus have infinite solutions
