Question 591363: Hi! I am having problems with this problem:
it says find the equation of the line which satisfies each set of conditions:
- passes through the point with coordinates (-2,1) and is parallel to the line, 3y-x=9.
this is what I have got so far
3y-x=9
3y(o)=9
3y=9
3y/3=9/3
y=3 (0,3)
3(0)-x=9
x=9 (9,0)
I dont know if it is correct and what to do next, can anybody help me please?

You can put this solution on YOUR website!
parallel means that the ratio of the coefficients (slope) is the same

you can use the same equation, after substituting the new point to find the new constant term (the 9)

3(1) - (-2) = ? ___ 5 = ?

3y - x = 5
