Step-by-step explanation:
The 1st equation is in slope-intercept form.
=> Slope = 4
The 2nd equation is in point-slope form.
=> Slope = -1/4
Since their slopes are unequal,
The lines are not parallel to each other.
However the product of their slopes is -1,
Therefore the lines are perpendicular to each other.
The answer is the 2nd option.
