Question

Graph of equations :
2x - y -7 =0

Answer 1

(1).here the equation is 2x-y-7=0

put x= 2 in the equation 2x-y-7=0 we get

2(2)-y-7=0 on solving that we get

4-y-7=0

y=4-7

y=-3

(2).put y=7in equation 2x-y-7=0 we get

2x-7-7=0

2x=14

x=14/2 we get

x=7

(3). put x=8in equation 2x-y-7=0 we get

2(8)-y-7=0

16-y-7=0

y=16-7

y=9

(4).put y=9 in equation 2x-y-7=0 we get

2x-9-7=0

2x=16

x=16/2

x=8

that solve.
