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.
