Answer:
Option (2)
Step-by-step explanation:
Let the equation of the line is,
y - y' = m(x - x')
where (x', y') is a point lying on the given line.
And m = slope of the line =
Line given in the graph passes through two points (-5, -1) and (-2, -3).
Slope of the line 'm' =
=
Therefore, equation of the line passing through(-5, -1) and slope of the line = will be,
y - (-1) =
