E. x - y = 2

In this problem, we are looking whether the Line pass through third quadrant . conceptually , any line that has Positive slope (Upward slope) will pass through third quadrant , that is, the line has either x or y or both coordinate points as negative .
We have to find the line in the choice that has negative slope and Positive y - intercept that is , it doesn't pass through the third quadrant
Only Choice C written in slope intercept form satisfies the condition .

Alternatively , you can substitute " Zero " for x and y in each equation to find the x and y coordinate points.
Only Choice C has both x and y coordinate points has Positive .

for this question you have to just find the slope of the each line. If the slope of the line is negative that it will not pass through 3rd quadrant.

Convert the each line to y=mx + C form . In this m is the slope of the line. if for any line m is negative that will be our required answer.

Detailed Explanation of why we are searching for the line whose slope is negative and that will be the answer- Please see the attachment

Also, slope is nothing but the angle made by a line with the x- axis in anticlock wise direction.

Solve using the options. Try an find -ve Y for a -ve X. Only option C doesn't provide that. Hence C

BOTH X AND Y INTERCEPT NEGATIVE MEANS SLOPE SHOULD BE POSITIVE.ARRANGE EQUATION IN Y=MX+C FORM AND YOU WILL SEE ONLY C GIVES NEGATIVE SLOPE

Hi Rollroll
Correct me if i'm wrong, there's still a case which x and y intercept negative and slope is ALSO NEGATIVE. Try y=-3/5x - 2/5.
