Line j passes through points (6, 63) and (5, -18). line k is parallel to line j. what is the slope of line k?

81

Step-by-step explanation:

Line j is parallel to line k.

So, the slope of those two straight lines will be the same.

So, y = mx + c and y = mx + c' are the equation of two parallel lines as the slopes of those lines are the same m.

Now, line j passes through points (6,63) and (5,-18).

Therefore, its slope will be .

Hence, the slope of the line k will also be 81. ( Answer )

395.84
