Question

Draw the graph of (i) x+2y=18
(ii) 2x+y=6
(iii) y=5x
(iv) x-y=6

Answer 1

Step-by-step explanation:

so firstly we have to find the coordinates of the graph ,lets find:

i).x+2y=18

x=18-2y

x=18-2(2)

x=18-4

x=14

so x=14 and y=2...........1st

x=18-2(4)

x=18-8

x=10

so x=10 and y=4.......2nd

so 1st and 2nd are the coordinates of the graph , so by using this draw the graph.

ii).2x+y=6

x=6-y/2

x=6-2/2

x=4/2

x=2

so x=2 and y=2.......1st

x=6-4/2

x=2/2

x=1

so x=1 and y =4....2nd

so 1st and 2nd are the coordinates of the graph just draw the graph by using this coordinates. .

iii).y=5x

y=5×1

y=5

so ,x=1 and y=5......1st

y=5x

y=5×0

y=0

so ,x=0 and y=0.....2nd

so by using 1st and 2nd coordinates draw the graph...

iv).x-y=6

x=6+y

x=6+1

x=7

so ,x=7 and y=1.....1st

x=6+y

x=6+0

x=6

so ,x=6 and y =0......2nd

so by using 1st and 2nd coordinates draw the graph..

u can also find 3 solutions for drawing the graph.....

thank you.. hope this will help you ......
