Answer:
Hello, this is not phythagoras, because phythagoras theorem needs a right triangle, but sorry I can't give full working out explanation, because I still haven't learned the trigonometry.
The slope intercept form is y=-7x+59
Step-by-step explanation:
y-y=m(x-x1)
y-3=-7(x-8)
y-3=-7x+56
+3 +3
y=-7x+59
360 degrees divided by that order
