Explanation:
5x+8y=9 ----- (1)
2x+3y=4 ----- (2)
From equation (1) assume the values of x and y to satisfy the equation to zero.
5x+8y−9=0 ------ (3)
Put x=5,y=−2 in equation (3)
5(5)+8(−2)−9=0
25−16−9=0
25−25=0
0=0
Again, put x=1,y=0.5 in equation (3)
5(1)+8(0.5)−9=0
5+4−9=0
9−9=0
0=0
Now plotting (5,−2),(1,0.5) and joining them, we get a straight line.
From equation (2) assume the values of x and y to satisfy the equation to zero.
2x+3y=4 ----- (4)
Put x=5,y=−2 in equation (4)
2(5)+3(−2)−4=0
10−6−4=0
10−10=0
0=0
Again put x=2,y=0 in equation (4)
2(2)+3(0)−4=0
4−0−4=0
4−4=0
0=0
Plotting (5,−2),(2,0) and joining them, we get another straight line.
