Question

guys help me please im in danger!!
.
Find the slope of the line that passes through the points (3, -6) and (6, 12).

Answer 1

m=(y2-y1)/(x2-x1)

Answer 2

ok dnt leave me stay here wen im done solving it

Answer 3

slope of a line: (y1-y2)/(x1-x2), plug in the values

Answer 4

m=(12-(-6))/(6-3)
= 18/3
= 6

Answer 5

@privetek is it y2-y1 or y1-y2? look at the way @emilie.li told me

Answer 6

it's (y2-y1)/(x2-x1 )

Answer 7

it doesn't matter if it's y1-y2 or y2-y1 as long as you keep it consistent for both the x and y values.

Answer 8

yes, i guess @emilie.li is right.. :)

Answer 9

that means that you can't write (y1-y2)/(x2-x1) because you won't get the right answer for the slope

Answer 10

so @emilie.li @privetek answer was wrong?

Answer 11

your answer is right, I was just saying that you have to be consistent with how you subtract the values for both x and y.
