Answer:
y = -3x + 5
Step-by-step explanation:
(y2-y1)/(x2-x1)
Plug coordinates into that
Then plug one of the coordinates into y = -3x+b to get b
This is a right triangle
We will use the Pythagorean theorem
a^2 + b^2 = c^2
If this is true it is a right triangle
5^2 + 12^2 = 13^2
25+144 = 169
169 =169
This is true so this is a right triangle
(x-3,y-4) = correct
y+20
20+y=y+20
