Question

Distance between (4, –1) and (8, –1)?

Answer 1

4

Explanation:

X1 = 4

X2= 8

Y1 = -1

Y2= -1

Distance Formula = √(X2-X1)² + (Y2-y1)²

Step 1. calculate (X2-X1)²

(8 - 4)2 = 16

Step 2. calculate (Y2-Y1)²

(-1 - -1)2 = 0

Step 3. calculate √16 + 0

= 4

Answer 2

Answer: 4

Step-by-step explanation: compute the distance between (x1, y1), (x2, y2):

(8 -4)² + [ -1 - (-1) ]² = 4
