The equation of the given line is
Where: The slope is -1/3
Perpendicular lines have additive reciprocal slopes which means if the slope of one of them is m, then the slope of the other is -1/m
Then the slope of the perpendicular line to the given line is 3
So, we have to look for the graph of positive slope
The graphs of A and D have positive slopes because the directions of the lines are increasing from left to right
Then we have to find the slope of each line to find the correct choice
Since the slope of the line is 3, then the y part increases 3 units for 1 part increases of x
We can see that in graph A
The answer is A
