Answer:
To find the distance, use the equation:
distance = √(x1 - x2)^2 + (y1 - y2)^2
using that equation we can plug in our known values, and solve
√(1 - 2)^2 + ( 3 - (-4))^2
√(-1)^2 + (7)^2
√(1) + (49)
√50
to find the square root of 50, we have to rationalize. we can separate the 50 into √25 and √2, which would give us 5√2.
hope this helps!
