i need to know how to solve things like:What is the slope of the equation 3y = 9 - x, note: i am NOT looking for a answer, i want a solution on how to find the answer please
pooja195
  • pooja195
to isolate y u need to divide everything by 3 \[\huge~\rm~\frac{ 3y=-x+9 }{ 3~~~~~~~~~~3~~~~~3 }\]

Looking for something else?

rearrange the equation into y = mx+b and then divide everything by 3 like what @pooja195 mention.

do u get what slope is now?
dan815
  • dan815
slope tells you the change in height for 1 unit change in x

we dont care what points we pick on the line, because that proportion will always be the same

as they are all similar triangles along this line

also bear in mind regard the x-axis in the independent axis and y-axis is the dependent axis.
