Do i have to reduce it or no or its actually wrong answer?

anonymous · Answer

All selected answers are correct..

anonymous · Answer

really.. but its saying that its wrong?

anonymous · Answer

For the first screensot, something is wrong. It should be 4/6 or 2/3 not -4/6

anonymous · Answer

$$Slope = \frac{y_2-y_1}{x_2  - x_1}$$

anonymous · Answer

It also says that you should have it in SIMPLIFIED improper form.

anonymous · Answer

Ya there is a minus mistake...

anonymous · Answer

These can be simplified to these.
Question 4: -3
Question 5: 3/2

anonymous · Answer

screenshot 12: slope=y2 - y1/x2 - x1
                                 = -4-0/6-0
                                 = -4/6
yes, all  selected  answers  are  correct.

anonymous · Answer

@sancy,
We take in order..

if you doing y2 - y1 then we should take x2 - x1 and not x1 - x2..

anonymous · Answer

so i have to reduce it.. 
because i know the answer is right but its saying that its wrong

anonymous · Answer

Yeah.

SCREENSHOTS FOR THE WIN!

anonymous · Answer

@waterineyes......that's what i   wrote....pliz check first before proceeding.....thnx

anonymous · Answer

@Sancy but you are not solving according to the formula..

anonymous · Answer

(x1, y1) = ((6, 0)
(x2, y2) = (0, -4)


Slope = (-4-0)/(0-6)

Slope = (-4)/(-6) = 4/6 = 2/3

anonymous · Answer

You have to use the x and y-coordinates in the same order @Sancy 
(0, -4) and (6, 0)
$$\frac{0 - (-4)}{6 - 0} = \frac{4}{6} = \frac23$$

anonymous · Answer

o.k now i got it...thnx by the way.....
