so it goes from
3x+y-1=0 to first:
moving the 3x to after equal sign making
y=-1=0+3x
then move the -1 to after equal sign with + sign to get rid of it in left side making
y=0+3x+1 correct?
then simplified to y=3x+1
so that's
k=3
m=1
correct or not? :) seems to make more sense now atleast
sorry but nope
in your first paragraph you've added a 2nd equals sign. There should never be a second on in this sort of problem
You are simply adding or subtracting from each side in order to get y alone.
So think, if you have y +3x -1 = 0, what must you do to each side in order to get y on its own (as in the from we desire).
You clearly must subtract 3x, so do that on BOTH sides of the equals sign. Now you are left with
y - 1 = -3x.
Next to get y alone we must add 1 to BOTH sides
After this we are left with y = -3x +1 which is in k from where k = -3 and m = 1
