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.

To find the slope of a line that passes through two points, you can use the formula:
slope = (change in y-coordinates) / (change in x-coordinates)
Let's apply this formula to the given points:
Given points: (-12.5, 3.2) and (-15.5, -7.2)
Change in y-coordinates = (-7.2 - 3.2) = -10.4
Change in x-coordinates = (-15.5 - (-12.5)) = -3
Now, we can calculate the slope:
slope = (-10.4) / (-3) = 10.4/3
So, the correct answer is 10.4/3 (or approximately 3.4667).
Your answer of -10.4/-3.5 is close, but it seems there was a small calculation error.
Remember, if you have any two points (x1, y1) and (x2, y2) on the line, the slope can be found using the formula:
slope = (y2 - y1) / (x2 - x1)
