The answer is A,
Comment the correct answer.
Answer: y = -2x +3
slope intercept form: y = mx +b
divide everything by 6.
2x = 3 - y
isolate y by subtracting 3 from both sides
2x - 3 = -y
divide by negative 1 to get positive y
-2x +3 = y
So you're using the Pythagorean theorem which is a^2 + b^2 = c^2... so if you dont have b you can manipulate the equation. That equation is c^2 - a^2= b^2, so you square 47 which is 2209 and then square 13 which is 169... you do 2209-169 and that equals 2040, then you do the square root of that which is 45.166359 that can be simplified to 45 or two decimal points 45.167. Hope that Helped! :)
