so if you are given the equation of a line y=mx +c, can you recognize what its slope is?
anonymous
  • anonymous
the slope would be m
baru
  • baru
yep, now what you have to do is : that the four options are in the form y=mx +c, except you have "s" instead of y, and "d" instead of x
baru
  • baru
so re-arrange the equations till you get them in y=mx +c form

with me so far?
anonymous
  • anonymous
yes but you put + its meant to be - there is no + in the answers given
baru
  • baru
think of it this way: the varibles m and c can be positve or negative, so you might get y=mx +c or y=-mx-c or y=mx-c too
baru
  • baru
if you have got y= -mx + c it just means that the slope is a negative number
baru
  • baru
making sense?
anonymous
  • anonymous
so the final answer would be c?
baru
  • baru
you mean the third option? for the first question... no
anonymous
  • anonymous
so its the last option?
baru
  • baru
yep
anonymous
  • anonymous
ok and any idea on the second one?
