What is the intersection of the lines given by $2y=-x+3$ and $-y=5x+1$? Enter the answer as an ordered pair.
2y = -x + 3 or y = -1/2 x + 3/2
y = -5x - 1
where they intersect they are equal....so equate them
-1/2 x + 3/2 = -5x-1
4 1/2 x = - 5/2
x = -5/2 / 4 1/2 = -5/2 * 2/9 = -5/9 this is 'x' put this value in one of the equations to compute 'y'
