in a cartiesian plane the linear equation 2y-7=0 represents
1) a unique point y =7 by 2
2) a line parallel tp x axis
3) a line parallel to y axis
4) none of these
2y-7=0
2y=7
y= 7/2
Any line of the form y= b is a line parallel to x-axis at a distance of "b" units from it.
So, y= 7/2 is a line parallel to x-axis at a distance of 7/2 units from it.
So the answer is (2)
