Answer: The answer is (b)
Step-by-step explanation: The equation of a straight line in slope-intercept form is given by
where, 'm' is the slope and 'c' is the y-intercept of the straight line.
The equation of the given line EF is
Here, slope, m=2 and y-intercept, c=1.
Since our new line is parallel to the given line, so the slope of the new line=m=2.
So, let the equation of the new line be
Now, since the line passes through the point (0,2), so
Thus, the equation of the new line parallel to line EF will be
The correct option is (b).
