Question 98515: Great lessons on graphing available in this section. However, Im still having a little difficulty with converting known points to an equation. Is this one y=mx+b? Thank you. Here's the the problem as written.
Find the equation of a line which passes through the point (0,5) and has a slope of -6/7.
I came up with the equation as y-5=-6/7(x-0) but I still feel as if I missed a step.
Thank you.

You can put this solution on YOUR website! I'm not sure what form they want it in, so I'll assume  form
If you want to find the equation of line with a given a slope of  which goes through the point ( , ), you can simply use the point-slope formula to find the equation:
---Point-Slope Formula---
 where  is the slope, and ) is the given point
So lets use the Point-Slope Formula to find the equation of the line
 Plug in  ,  , and  (these values are given)
 Distribute
 Multiply and to get
 Add 5 to both sides to isolate y
 Combine like terms and to get
------------------------------------------------------------------------------------------------------------
Answer:
So the equation of the line with a slope of which goes through the point (,) is:
which is now in form where the slope is and the y-intercept is 
Notice if we graph the equation and plot the point (,), we get (note: if you need help with graphing, check out this solver)
 Graph of through the point (,)
and we can see that the point lies on the line. Since we know the equation has a slope of and goes through the point (,), this verifies our answer.
