What is the slope of the line that passes through (-12.5,3.2)(-15.5,-7.2)?

I think the answer is: -10.4/-3.5.

Not sure on this one

(-12.5,3.2),(-15.5,-7.2).

m = (-7.2-3.2)/(-15.5-(-12.5))
m = -10.4/-3 = 3.47.

To find the slope of a line passing through two points, you can use the formula:

slope = (y2 - y1) / (x2 - x1)

Let's apply this formula to the given points (-12.5,3.2) and (-15.5,-7.2):

x1 = -12.5
y1 = 3.2
x2 = -15.5
y2 = -7.2

Now we can plug these values into the formula:

slope = (-7.2 - 3.2) / (-15.5 - (-12.5))
= (-10.4) / (-3)
= 10.4 / 3

So the slope of the line passing through the points (-12.5,3.2) and (-15.5,-7.2) is 10.4/3.
