The answer choice are -6, 9, 7, 15 ​

Step-by-step explanation:

the answer is 7 because there are seven spaces in between

The Distance = √(y2-y1)² + (x2-x1)²

Notice

The points occur at the same x value (-6)

So We don't have to both about this cos the change will be zero(x2-x1)

Why?

(-6-(-6) = 0.

So we're concerned with the y value

y1= -2

y2= -9

(y2-y1) = -9-(-2) = -9+2 = -7

d= √(-7)²

= √49

=7.

The Third Option is correct.

step-by-step explanation:

it's is b

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.
