only smart ppl
@jim_thompson5910
are you familiar with the slope formula?
no
slope formula \[\Large m = \frac{y_2 - y_1}{x_2 - x_1}\] hopefully you've seen something like this in your lesson/notes somewhere?
yes i remeber
so you'll need to find the slope of each line segment
wow all of them?
pretty much yes
nice name
yes all of them. I'll get you started on a few of them ------------------ line segment AB A = (x1,y1) = (-3,1) B = (x2,y2) = (-1,3) slope of AB \[\Large m = \frac{y_2 - y_1}{x_2 - x_1}\] \[\Large m = \frac{3-1}{-1-(-3)}\] \[\Large m = \frac{3-1}{-1+3}\] \[\Large m = \frac{2}{2}\] \[\Large m = 1\] Slope of line segment AB is 1 ------------------ line segment BC B = (x1,y1) = (-1,3) C = (x2,y2) = (3,3) slope of BC \[\Large m = \frac{y_2 - y_1}{x_2 - x_1}\] \[\Large m = \frac{3-3}{3-(-1)}\] \[\Large m = \frac{3-3}{3+1}\] \[\Large m = \frac{0}{4}\] \[\Large m = 0\] Slope of line segment BC is 0 ------------------ line segment CD B = (x1,y1) = (3,3) C = (x2,y2) = (2,0) slope of CD \[\Large m = \frac{y_2 - y_1}{x_2 - x_1}\] \[\Large m = \frac{0-3}{2-3}\] \[\Large m = \frac{-3}{-1}\] \[\Large m = 3\] Slope of line segment CD is 3
ok jimmy i see how to do it thank u
