Answers
Step-by-step explanation:
at x = 0, y = 0at x = - 1, y = -1 [(-1, 1) point is not satisfied]Therefore, the equation does not follow the graph.
(ii) x + y = 0
at x = 0, y = 0at x = -1, y = 1at x = 1, y = - 1All the points are satisfied and Hence, the equation follows the graph.
(iii) y = 2x
at x = -1, y = - 2 [ (-1, 1) point is not satisfied]Therefore, the equation does not follow the graph.
(iv) 2 + 3 y = 7 x
at x = 0, y = -2/3 [(0, 0) point is not satisfied]Therefore, the equation does not follow the graph.
In figure 4.7, points are (-1, 3), (0, 2) and (2, 0)
Hence,
(i) y = x + 2
at x = - 1, y = 1 [(-1, 3) point is not satisfied]Therefore, the equation does not follow the graph.
(ii) y = x - 2
at x = -1, y = -3 [(-1, 3) point is not satisfied]Therefore, the equation does not follow the graph.
(iii) y = - x + 2
at x = -1, y = 3at x = 0, y = 2at x = 2, y = 0Therefore, all the points are satisfied and the equation follows the graph.
(iv) x + 2 y = 6
at x = - 1, y = 7/2 [(-1, 3) point is not satisfied]Hence, the equation does not follow the graph.
Advice :-
I Think U Forgot To Put The Graph
And The Question Is So Messed Up
Put The Graph First.
Definition:-
The aim of a well-written case study in Mathematics is to provide guides and teachers with important information on any number of situations that are problematic..... As a student, your case study should articulate your research goals very carefully and then go on to give good methods and a proper conclusion.
