(My answer)

OR

**Q#2**
If the line of equation is

Shouldn't we be able to find out the value of

**y** for it's corresponding value of

**x**? I mean if I am 100% sure that at a certain point, in my question where the above line is intersecting with the y-axis, thus x = 0, right?

So if I put x=0 in the above equation, my value for the corresponding y comes as 1. But in the answer of the question the examiner has taken the value of y as the y-intercept.

Please explain what am I doing wrong.

Thanks in advance!
