Answer:

$\frac{2}{7}$

Step-by-step explanation:

In order to find the slope of a line you must find where the points intersect, use the formula for slope, substitute values, and simplify if needed.

In this case we were already given the points for slope:

$P1=(-4,-4) = (x1,y1)$

$P2=(-2,3)=(x2,y2)$

Slope formula:

$slope = \frac{y2-y1}{x2-x1}$

Now substitute:

$\frac{-2--4}{3--4}$

Solve using KCC: (Keep, Change, Change)

$-2+4=2$

$3+4=7$

= $\frac{2}{7}$

Because the slope isn't a negative you do not need to simplify the answer.

Hope this helps.
