The other equation could be
2y - 6x = -6
Solving:-
y - 3x = -3..........(1)
2y - 6x = -6........(2)
multiplyng the first equation by 2 gives
2y - 6x = -6
so equations (1) and (2) are the same equation
If we graph them they will be the same line
Every point on that line will be a solution.
So there are infinitely many solutions
The coordinates are (-4,0),(0,-1)
The answer to this question is going to be negative 6
70 Miles = 112.65408 Kilometers
Y - 6 = 10(x - 2) hope this helps :)
