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:
<span> </span>
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.
