Answer:
For checking which line is farther from origin we can find out individually the perpendicular distances to these lines from the point of origin.
So, for finding perpendicular distance to a line ax+by+c=0 from point (h,k) the formula is,
d = |ah+ky+c|/√a^2+b^2
So,First distance of origin from line 2x-y+3=0 will be
d1 = |2(0)-1(0)+3|/√2^2 + (-1)^2 = 3/√5
And, the distance of origin from line x-4y-7=0
will be
d2 = |1(0)-4(0)-7|/√1^2+(-4)^2 = 7/√17
So, now on comparing values of d1 and d2 we find that d2>d1
So, second line x-4y-7=0 is farther from point of origin than the first line 2x-y+3=0.
Hope this helps you !
