And form a right angle at point b. if a = (-3, -1) and b = (4, 4), what is the equation of ?

a.
x + 3y = 16
b.
2x + y = 12
c.
-7x − 5y = -48
d.
7x − 5y = 48

exactly you go it

step-by-step explanation:

idk

step-by-step explanation:

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )
