Question
Ex 10.3 sum no.5 class xi maths. dear shanker sir, when i draw the same on a graph paper, i get the distance on the x axis as 1 and 7 since x coordinate is said to be 3 and y as 4. but when i work out according to the formaula it comes out tobe 8 and 2 why sir. could you show me a drawing on the graph showing the perpendicular from the x axis to the line.

The line x/3+y/4=1 intersects the Xaxis at the point(3, 0) and the Yaxis at (0, 4)
Thus the points on Xaxis at a distance of 4 units from the line are (8, 0) and (2, 0).
Graphically you must get the same points.
Plot the points (3,0) and (0,4) and join them to get the line.
Now draw a line perpenicular to the given line to intersect the Xaxis,
As you move the scale to the points (2,0) and (8,0) you will get exactly 4 units from the line.
