Question

The equation of this line is -

1. y = 2x + 6
2. y = 6x + 2
3. y --2x + 6
4. y = -6x + 2
5. None of these alternatives is
correct.

Answer 1

Explanation:

Graph ko dekh ke pata lagta hai ki

x = -3 pe y = 0

Now checking option ;

put x = -3 in each equation and check
1) y = 2(-3) + 6 = 0 ; which satisfies
2) y = 6(-3) + 6 = -12 ; which doesn't satisfies
3) y = -2(-3) + 6 = 12 ; which doesn't satisfies
4) y = -6(-3) + 2 = 20 ; which doesn't satisfies

Therefore ;
(1) is the correct equation of line.

There are many more methods to solve but from my opinion , this is the best way to solve these kind of questions .

Answer 2

The answer is 1. y=2x+6
