Question 1
What is the exact distance from (-1, 4) to (6,-2)? (4 points)
180 units
182 units
85 units
189 units

Respuesta :

Answer:

√85 units

Step-by-step explanation:

If we move from  (-1, 4) to (6,-2), we see x (the run) increasing by 7 and y (the rise) decreasing by 6.  

The distance between these two points is found using the Pythagorean Theorem:  

d =  √ [7² + 6²] = √85 units    (we cannot leave off the " √ " operator).  Compare this to the 3rd answer choice.
