When Slope line passing through unknown point(x,y) and (0,-6) or (8,0) is equal to Slope of line passing through points (0,-6) and (8,0) then that point lies on the given line.

Slope of line passing through points (0,-6) and (8,0)=$$\frac{0-(-6)}{8-0}$$=$$\frac{3}{4}$$

Let's check slope of line (0,-6) and (x,y) from answer options.

A. slope=33/44=3/4 DISCARD
B. Slope=9/8=3/4 DISCARD
C.Slope=6.75/9=3/4 DISCARD
D. Slope=3/4 DISCARD
E. Slope=12/2=6 KEEP

Ans. (E)

Hi sumit411,
Answer is E.

Hi PKN,

Can you please check option D and E again and let me know where I went wrong.

Regards,
Sumit

If you observe the line , you can see if x is between 0 and 8 , y cannot be positive.

From the line l, when x becomes less than 8, Y should be negative even if X becomes negative. when x becomes more than 8, Y should be positive. option E does not obey this. (2,6) is NOT a point on line l

Hi sumit411,
Answer is E.

Hey PKN

okay, i know slope is $$\frac{3}{4}$$

but what calculations did you perform to eliminate incorrect answer choices and leave a correct one ?

A. slope=33/44=3/4 DISCARD (how about here ? )
B. Slope=9/8=3/4 DISCARD (here I get, you reduce fraction )
C.Slope=6.75/9=3/4 DISCARD (And here ?)
D. Slope=3/4 DISCARD
E. Slope=12/2=6 KEEP (and here )

thank you

Hi dave13,
When Slope line passing through unknown point(x,y) and (0,-6) or (8,0) is equal to Slope of line passing through points (0,-6) and (8,0) then that point lies on the given line. This unknown point(x,y) is given in answer options.
A. slope of line passing through (0,-6) and (44,27)=$$\frac{27-(-6)}{44-0}$$=3/4 DISCARD
B. slope of line passing through (0,-6) and (12,3)=$$\frac{3-(-6)}{12-0}$$=9/12=3/4 DISCARD
C.slope of line passing through (0,-6) and (9,0.75)=$$\frac{0.75-(-6)}{9-0}$$=6.75/9=3/4 DISCARD
D. slope of line passing through (0,-6) and (4,-3)=$$\frac{-3-(-6)}{4-0}$$=3/4 DISCARD
E. slope of line passing through (0,-6) and (2,6)=$$\frac{6-(-6)}{2-0}$$=12/2=6 KEEP

Since A,B,C, and D match the slope 3/4 , Hence these options are to be discarded as per question stem.

Ans. (E)

P.S:- You will get the same result if (x,y)=(8,0).
