Question

Find the slope of the line that passes through the pair of points. (–5.5, 6.1), (–2.5, 3.1)

Answer 1

ANSWER
The slope is
$- 1$


EXPLANATION

The slope of the line that passes through,

$(-5.5,6.1),(-2.5,3.1)$
can be found using the formula,

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

So we let,

$(x_1,y_1)=(-5.5,6.1)$

and

$(x_2,y_2)=(-2.5,3.1)$


We substitute them into the formula to get,

$slope = \frac{ 3.1 - 6.1}{- 2.5 - - 55}$
This gives us,

$slope = \frac{ 3.1 - 6.1}{- 2.5 + 55}$
We simplify to get,

$slope = \frac{ - 3.0}{3.0}$


$slope = - 1$

Answer 2

,(6.1-3.1)/(-5.5-2.5) = 3/-8 = -3/8=-.375
