Question

how to find the slope of this equation
x + y = 7

Answer 1

ax+by+c=0 , the slope is -a/b so answer is -1

Answer 2

ok, were did the other variables "a" and "c" and "by" come from?? im completely confused now. where did the 7 go? and how did you get -1??

Answer 3

'a' and 'c' not variables.
x+y-7=0 then you should do -x's coefficient / y's coefficient , so -1/1=-1

Answer 4

y=mx+b where m is slope.
So x+y=7
y=-x+7=(-1)x + 7
m=-1
:D

Answer 5

thank u

Answer 6

cleared up some confusion
