Step-by-step 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
You can find “hypotenuse” using Pythagorean to get the length of one of those steps, 12.5, and you get 150 when you multiply that number by 12 for each of the 12 steps
