Question

Draw the graph of
x-y+1=0 ,3x+12y

Answer 1

.

Find the values of x and y

by filling one of them in both equations:-

Equations given:-

x-y+1=0-----------------(1)

3x-2y+12=0-------------------(2)

from equation 1,

When x=1

1-y+1=0

y=0

when x=2

2-y+1=0

y=3

From equation 2,

When x=1

3-2y+12=0

2Y=-15

Y=-15/2

WHEN x=0

6-2y+12=0

2y=-18

y=-18/2

y=9
