Question

What is the slope of the line between (3, −4) and (−2, 1)? (1 point) a 1 b 2 c −2 d −1

Answer 1

Answer:

(1+4)/(-2-3)= 5/-5= -1 is the slope

Answer 2

For this case we have that by definition, the slope of a line is given by:

$m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}$

In this case we have to:

$(x_ {1}, y_ {1}) :( 3, -4)\\(x_ {2}, y_ {2}): (- 2,1)$

Substituting we have:

$m = \frac {1 - (- 4)} {- 2-3} = \frac {1 + 4} {- 5} = \frac {5} {- 5} = - 1$

So, the slope is -1

ANswer:

$m = -1$
