find the slope, if it exists,of the line containing the pair of the points.
(-2,-11) and (-20,-15).
I came up with (-2,-9)is this correct?
slope is the change in y divided by the change in x.
Slope = (-11- -15)/(-2- -20)
Do the math and simplify and you wil have the slope.
I thought the formula i was suppose to use is y2-y1
x2-x1
which equals to
(-15,- -11)and(-20,- -2)
Then I got -4/-18 which equals to
-2/-9
To find the slope of a line containing two given points, you can use the formula:
slope = (y2 - y1) / (x2 - x1)
Let's apply this formula to the given points (-2, -11) and (-20, -15):
slope = (-15 - (-11)) / (-20 - (-2))
= (-15 + 11) / (-20 + 2)
= -4 / -18
= 2/9
So, the slope of the line containing the points (-2, -11) and (-20, -15) is 2/9.
The value you mentioned, (-2, -9), does not seem to be related to the slope calculation. It is important to double-check your work and ensure that the correct points are used in the formula.
