Answer:
or

Explanation:
The point-slope form equation is
, where,
(a, b) = a point on the line.

Given the two points, (6, 8) and (7, 1), find the slope of the line:



There are two possible point-slope equation we can come up with using each points on the line given.
Using the point (6, 8) and m = -7,
Substitute m = -7, a = 6, and b = 8 into


Using the point (7, 1) and m = -7,
Substitute m = -7, a = 7, and b = 1 into
