black i thought i was supposed to do 8-4 and 7-1?

- anonymous

yes.. i think so>? pooja right?

- Black_ninja123

y2 is -8 and y1 is 7
so -8-7= -15

- Black_ninja123

x2 is -4 and x1 is 1
-4-1=5

- anonymous

well anyway i dont do
y2= -8
y1= -4
x2 = 7
x1= 1
and then
-8-(-4)
7-1
and get -4/6?

y1=7
x2=-4
y2=-8
