(1,1) (5,6)
---
to solve the linear equation, copy and paste this (the two given points):
1,1,5,6
into the "Two-Point form: x1 y1 x2 y2" input box here: https://sooeet.com/math/linear-equation-solver.php
---
x-intercept = (0.2, 0)
y-intercept = (0, -0.25)
slope = 1.25
---
answer:
perpendicular lines have negative reciprocal slopes, so the slope of the perpendicular line is:
perpendicular slope = -1/1.25 = -0.8
