Answer:
3rd answer EF = 2√13
Step-by-step explanation:
Make a right triangle and use Pythagorean theorem a²+b² = c²
Go from point F 6 units down till point (1,-3) .From that point go 4 units left till you hit point E.
Triangle has legs a and b that are 6 and 4 units long so 6² + 4² = EF²
36 + 16 = 52
EF² = 52 find √52
EF = √52
There is no √52 as a whole number so rewrite 52 as a product of number who was a √ and the other who doesn't have a √
52 = 4 * 13
EF = √4 * √13 = 2√13

-2/21. the y intercept would be 5, considering the x is 0 on the first pair of coordinates. so y=-2/21x+5, or A
