Answer:
The slope is 
Step-by-step explanation:
Slope of a dataset:
The slope of a dataset, having two points, is given by the change in y values divided by the change in x values
In this question:
Two points:
x = 0, y = 8
X = 4, y = 13
The slope is:

The slope is 
Add 26 and 73 = 99 then divide 99 by 6 = 16.5 which is 17 vases
I guess positive bcuz - -=+
Its D because look if u add the white and red ones its 14 and all them together is 26 so it would be 14/26
AB=h can be found with
tan 60° =AB / AC, and AB=h= tan60° x AC
h= 14* 1.73=24.24
