Question

The graph of 3x + 2y = 6 meets the x-axis at point P and the y-axis at point Q. Use the graphical method,then the co-ordinates of points P and Q are P = (2, 0) and Q = (0, 3)
If true then enter 1 and if false then enter 0

Solution

To draw the graph for the given linear equation, we need to first plot
the points which lie on it, join them to get a straight line.
First equation is x+y=2=>y=x+2
Substitute different values of x in the equation and calculate to get corresponding values of y.
x
y=x+2
Point (x,y)
0
2(0,2)
20(2,0)
42(4,2)
13(1,3)
35(3,5)

Plot these points on the graph paper and join them using a straight line.
Second equation is x2y=5=>y=x252
Substitute different values of x in the equation and calculate to get corresponding values of y.
x
y=x252
Point (x,y)
0
52(0,52)
31(3,1)
50(5,0)
272(2,72)
34(3,4)

Plot these points on the graph paper and join them using a straight line.
Third equation is x3+y=0=>y=x3
Substitute different values of x in the equation and calculate to get corresponding values of y.
x
y=x3
Point (x,y)
0
0(0,0)
31(3,1)
62(6,2)
31(3,1)
62(6,2)

Plot these points on the graph paper and join them using a straight line.
All the three lines meet at a point. (3,1)
