Observe the graph, the line passing through the points
.
Find the slope of the line containing the above points.
\The slope formula is
.
The values of
are substitute in the slope formula.


The two parallel lines have same slope.
\So the required line containing slope is negative 2.
\The options are containing slope - intercept form of line equation,
.
Observe the option B, its line
has slope negative 2, so the required line is
.
The option B is correct answer.
