Question

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

Answer 1

81

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
`(-18-63)/(5-6) = 81`.

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