Imo E .

In a rectangular coordinate system, does the point (1,1) lie on line q?

(1) The slope of q is not 1.

Slope can be 0 or any other value .. Not sufficient .

(2) Line q does not pass through point (0,0).

It can pass through (1,1) or (2,1 ) . Not Sufficient .

Combining above .. also Not sufficient since the line may or may not pass through (1,1)

Stat1: The slope of q is not 1.
Slope = -b/a not equal to 1. We don't know, if line q passes through (1,1) or not. Not sufficient.

Stat2: Line q does not pass through point (0,0).
We don't slope and 1 point to determine line q. Not sufficient.

Combining both, line q can be any slope except 45 degree (m=1) and pass through any point except (1,1). So, again, Not sufficient..

So, I think E. :)

Point P(1,1)

(1) The slope of q is not 1.

Not sufficient as there may be line with slope not equal to one and passing through P


(2) Line q does not pass through point (0,0).

Not sufficient, there may be infinite line which do not pass through (0,0) and few of them may pass through P

Combined-no difference all the issues persist- Answer is E in my opinion

Does (1,1) lie on line q?

Statement 1:
Slope of q is not 1.
There are infinitely many lines whose slopes are not 1, and they can or cannot pass through (1,1).
Thus, (1,1) can or cannot lie on line q.
For eg: i. (1,1) lies on line x = 1 having slope \(\neq\) 1
ii. (1,1) does not lie on line x = 2 having slope \(\neq\) 1
Statement 1 is Not Sufficient.

Statement 2:
Line q does not pass through (0,0)
There are many lines, which do not pass through (0,0), and they can or cannot pass through (1,1).
Thus, (1,1) can or cannot lie on line q.
Examples in Statement 1 can be considered here [line x = 1 and line x = 2].
Statement 2 is also Not Sufficient.

Statement 1 and Statement 2 combined:
Slope of q is not 1 and Line q does not pass through (0,0).
There are infinitely many lines, whose slope is not 1 and which do not pass through (0,0), and they can or cannot pass through (1,1).
Thus, (1,1) can or cannot lie on line q.
Examples in Statement 1 can be considered here also [line x = 1 and line x = 2].
Statement 1 and Statement 2 together are Not Sufficient.

So, correct answer is option E.
