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?
