Answer:
a) yes
The point ( 1,-3) lie on the given line y = 5x-8
b) No
The point ( -2,-7) does not lie on the given line y = -3 x +1
Step-by-step explanation:
Step(i):-
a) Given line y = 5 x - 8 ...(i)
Point ( 1, -3 )
substitute ( 1,-3 ) in equation (i)
-3 = 5(1) - 8
-3 = 5 -8
-3 = -3
∴ The point ( 1,-3) lie on the given line y = 5x-8
b)
Given line y = -3 x +1 ...(i)
Point ( -2, -7 )
substitute (-2, -7 ) in equation (i)
-7 = -3(-2) +1
-7 ≠ 7
The point ( -2,-7) does not lie on the given line y = -3 x +1
