What is the slope of a line that passes through the points (-2, 4) and (-6, 12)

A)-2
B)-1/2
C)1/2
D)2

Slope = rise / run = (y1 - y2) / (x1 - x2) = (4 - 12) / (-2 - (-6)) = -8 / 4 = -2

The answer is A) -2.

The simplified way to answer this question is to show you this formula.

y+y2 (not multiplication)
------- <---- means division
x+x2

and your co-ords are x,y and x2,y2

so with your numbers plugged in we get

4 + 12 16
---------- =----
(-2) + (-6) -8

So your answer is 16 divided by -8 which is -2.
I hope this answer is useful for the simplified formula.

To find the slope of a line that pass through (x1,y1) and (x2,y2)

Just divide the difference of the y values by the difference of the x values:

deltay / deltax ==> (y2-y1) / (x2 -x1)

Then the slope is: (12-4) / (-6-(-2)) = 8/(-4) = -2 OK!

Answer:
------------
slope = m

m = y2 -y1 / x2 - x1 = 12 - 4 / - 6 - (- 2) = 8 / - 4 = - 2

Final Answer is A) - 2

-2

it is (12-4) / (-6+2)

m= (12-4)/ ( -6-(-2))
m= 8/-4 = -2 AnsW A

12-4=8 -6--2=-4 8/-4=-2 so A
