Question

What is the system of equations that describes the following graph?
Answers:

4x + y ≤ 2
x + 3y ≥ 1

4x + y ≥ 2
x + 3y ≥ 1

4x + y ≤ 2
x + 3y ≤ 1

4x + y < 2
x + 3y > 1

Answer 1

Last one

Answer 2

as usual we need to find the equations of red lines first

Answer 3

but these are neither vertical nor horizontal - they're slanted, so... how do we find them

Answer 4

Thats the hard part

Answer 5

theres a easy way out

Answer 6

look at the options,

Answer 7

we're very very lucky. all options are same, except for the inequality !

Answer 8

ok

Answer 9

so equations will have to be :-
4x + y = 2
x + 3y = 1

Answer 10

lets try to find out, which belongs to which red line

Answer 11

alrite

Answer 12

look at graph, and tell me which line is steepest

Answer 13

the steepest is the y axis?
