Answer:
the slope is 1/2
Work:
if the x-coordinate is two times the y-coordinate, that means you are going up one over two each time
slope= y2-y1/x2-x1
so you can pick two points, like (2, 1) and (4,2) and use the formula
slope= 2-1/4-2= 1/2
The solution is in parenthesis, so this means the numbers are included in the answer. Since the first number is 2, 2 is a possible answer so the circle at positive two would be solid.
The other solution is infinity, so the answers are any number to the right of the 2 on the number line.
This makes the answer: A solid circle appears at positive 2. The number line is shaded between positive 2 and positive 5.

if 8 is a whole (100%) and 16 is twice of that, you can conclude that her speed increased by 200%
