2. y = -5/3 x + 10/3
3. 3y = –5x + 10
4. 3x + 15y = 30
5. 5x + 3y = 10

The equation y=x-2 do not represents the line that passes through the two point, since for example -4-2=-6, not 10. So (-4,10) is not on the line.
Let find the equation of the line:
First compute the slope using formula:
So the equation is in the form:
For x=-4 we get the equation:
Solving the above equation for s we get:
The equation then is the following:
The correct answer then is equation 2 and equation 3.
