Question

Find the slope of a line parallel to the line through the given points.

P(-2, 4), Q(6, -2)



A. 4/3
B. 3/4
C. -3/4

Answer 1

what would be the slope of this line -> P(-2, 4), Q(6, -2) ?

Answer 2

@jdoe0001 i have no idea i just copied and pasted the question and answer just like it is

Answer 4

parallel lines, have the same slope, so, you find the slope for that one, you'd find the slope for the other one

Answer 5

to find the slope, use this formula :
slope (m) = (y2 - y1) / (x2 - x1)
set 1 (-2,4) set 2 (6,-2)
Lets plug our info into the formula
m = (-2 - 4) / (6 - (-2)
can you take it from here ?

Answer 6

Im guessing we multiply-2*-4 and 6*-2

Answer 7

no...add

Answer 8

ohh so it would be -2+(-4) and 6+(-2) ?

Answer 9

yes

Answer 10

so -6,4

Answer 11

rise OVER run

Answer 12

wait..no.....-2 + (-4) and 6 - (-2)
-6 / 8 ...do you understand how I got this answer ?

Answer 13

two negatives equal a positive

Answer 14

-6/8 reduces to what ?

Answer 15

-3/4

Answer 16

BINGO.....your answer is -3/4. Since the lines will be parallel, the slope will be the same. If it was perpendicular, then it would be different.

Answer 17

awesome thanks a lot ! :)

Answer 18

anytime :)
