Answer 1

Slope of a line passing through two points (x1, y1) and (x2, y2) is
\[\frac {y2-y1}{x2-x1}\]
(x1, y1)=(3, -7)
(x2, y2)=(-1, 1)
Can you solve this @miah ?

Answer 2

yeah,

Answer 3

1.5 ?

Answer 4

\(\frac{1-(-7)}{-1-3}\)
\[\frac{8}{-4}\ne 1.5\]

Answer 5

so, undefined ?

Answer 6

\[\frac{-8}{4}=???\]

Answer 7

I meant that you have did some wrong calculation

Answer 8

-2

Answer 9

Yes
