Given : -2x + y - 7 = 0
To Find : Draw graph
Check whether point ( - 3, - 2 ) lies on line or not
Solution:
-2x + y - 7 = 0
=> -2x + y = 7
=> --2x/7 + y/7 = 1
=> x /(-7/2) + y/7 = 1
Hence two points are ( -7/2 , 0) and ( 0 , 7)
check (-3 , - 2)
-2(-3) + (-2) - 7 = 6 - 2 - 7 = - 3 ≠ 0
Hence point does not lie on line
