Question

Which of the following is the slope between the points (-2, 4) and (2, -2)?

A. -3:2
B.-2:3
C.3:2
D.2:3
I dont understand this? Can you please help me?

Answer 1

The slope of the line through points (x1,y1) and (x2,y2) is given by :
\(\huge m=\frac{y_1-y_2}{x_1-x_2}\)
now,just put the values and find m.

Answer 2

hmmmm

Answer 3

from -2 to 2 is 4 units right. this is your denominator, 4
from 4 to -2 is 6 units down. your numerator is -6 (minus, because it is down)
ratio is \(-6:4\) or \(-3:2\) by removing the common factor of 2

Answer 4

lol wuttt. @Hero cuz at first you say 2/3 then you say 3/2! im confused!

Answer 5

That's because I keep making sign errors, sorry.

Answer 6

Now, I'm agreeing with Satellite:

4 = -2m + b
-2 = 2m + b

b = 2m + 4
b = -2 - 2m

b = b

2m + 4 = -2 - 2m

2m + 2m = -2 - 4
4m = -6
m = -6/4
m =- 3/2
