which two points does this line go through

jimthompson5910 (jim_thompson5910):

what is the slope of the line going through (2,-2) and (4,2)

OpenStudy (anonymous):

I am not quite sure what to do next

jimthompson5910 (jim_thompson5910):

use the slope formula m = (y2 - y1)/(x2 - x1)

jimthompson5910 (jim_thompson5910):

yep, keep going

jimthompson5910 (jim_thompson5910):

keep going

jimthompson5910 (jim_thompson5910):

no

jimthompson5910 (jim_thompson5910):

-2 -2 isn't 0

jimthompson5910 (jim_thompson5910):

so it turns into -4/(-2) = ???

OpenStudy (anonymous):

2

jimthompson5910 (jim_thompson5910):

that's your slope, so m = 2

jimthompson5910 (jim_thompson5910):

y = mx+b y = 2x + b

jimthompson5910 (jim_thompson5910):

now plug in one point and solve for b

jimthompson5910 (jim_thompson5910):

yes hopefully you know how to find the -6 and you're not just getting this answer because it's the only answer choice with a slope of 2

thank you!!!!
