Find the slope of the line.
(1,4) (2,1)
A.-3
B.3
C.-1/3
D.1/3
please help!
m = tan θ = ( y2 - y1 ) / ( x2 - x1 )
m = tan θ = ( 1 - 4 ) / ( 2 - 1 ) = - 3 / 1 = - 3
If you have more questions like this go on:
wolframalpha.c o m
when page be open in rectangle type:
slope and coordinats
in this case type:
slope (1,4) (2,1)
then click option =
you will see answer
I don't know is it -1/3?
I see Bosnian gave you a very detailed explanation when he answered
your previous question, which is almost identical to this one.
Show me how you worked it out, and and will reply.
wolframalpha.com doesn't work :(
To find the slope of a line given two points, you can use the formula:
slope = (change in y)/(change in x)
In this case, you have two points: (1,4) and (2,1).
To find the change in y, subtract the y-coordinates of the two points:
change in y = 1 - 4 = -3
To find the change in x, subtract the x-coordinates of the two points:
change in x = 2 - 1 = 1
Now, plug these values into the slope formula:
slope = (-3)/(1) = -3
Therefore, the slope of the line passing through the points (1,4) and (2,1) is -3.
So, the correct answer is A. -3.
