Answer:
Step-by-step explanation:
Line is passing through the point
and has slope (m) = - 9
General equation of line in point slope form is given as:
Therefore
This is the required equation of line in point slope form.
Answer:

Step-by-step explanation:
Given

Required
Determine x2, y2
Start by splitting the expression
and 
Solving for x2 in 
Multiply through by 2


Make x2 the subject;

Similarly:

Multiply through by 2


Make y2 the subject;

Hence:

2x+3y=6
subtract 2x from both sides.
3y=6-2x
divide by 3 on all sides.
y=2-2/3x
