Answer:
Explanation:
Let D = distance between the points (-7, 7) and (-7 , 8)
To find the distance between the points (-7, 7) and (-7 , 8), we simply use the formula D = 

 -7 
 = 7 
 = -7 
 = 8
D = √ (-7 - -7)² + (8 -7)²
 =√ (-7+7)² + (8 -7)²
 =√ 0² + 1²
 =√1²
 =1
D = 1
Therefore the between the points (-7, 7) and (-7 , 8) is 1
