Only the second line!

anonymous · Answer

If you can solve 1, then you can solve second one also..

vocaloid · Answer

point slope formula:

(y2-y1) = m(x1-x2)
solve for m by using the points (x1,y1) and (x2,y2) by plugging in the values for x1,x2,y1, and y2

anonymous · Answer

i didn't line one is a different question lol

anonymous · Answer

I know, but they are one and the same concept based question. If you can find the slope of first, then by using same formula, you can find second one too. :P

anonymous · Answer

i didn't the first line is the wrong problem (the next question)

anonymous · Answer

Slope is given by:
$$Slope = \frac{y_2 - y_1}{x_2 - x_1}$$

anonymous · Answer

so 3/17?

anonymous · Answer

How, show me first..

anonymous · Answer

y2-y1 =3
-------
x2-x1= 17

anonymous · Answer

Okay, what is y2 value and what is y1 value there?

anonymous · Answer

-5 minus -8
