Answer:
The equation for line k is
Step-by-step explanation:
The equation of a line has the following format:
In which m is the slope.
When two lines are perpendicular, the multiplication of their slopes is -1.
The equation for line j can be written as y =1/2x-1
Since k is perpendicular to j, and the slope of j is 1/2, the slope of k is:
So
It passes through the point (6,-6).
This means that when . So
So
