1/25 i don’t know if this is right but here you go
Answer: 1/2
Explanation: The slope of the given line y = 1/2x+3 is 1/2 as its the coefficient in front of the x. Any line parallel to this will also have a slope of 1/2. Parallel lines have equal slopes. The info about (10,0) is unneeded. It was likely put in there to throw you off.
All three of them do exist on the line y = 2.5x + 4
In order to find the answer to this question, start by finding the line for two points. For this example, we'll use A and C.
First we need to find the slope.
(y1 - y2)/(x1 - x2)
(9 - -1)/(2 - -2)
(9 + 1)/(2 + 2)
10/4
2.5
Now using slope intercept form and point A, we can determine the intercept of that line as well.
y = mx + b
-1 = 2.5(-2) + b
-1 = -5 + b
4 = b
So now we know A and C form the line y = 2.5x + 4. We can then check if B fits that line.
y = 2.5x + 4
4 = 2.5(0) + 4
4 = 0 + 4
4 = 4 (TRUE)
Therefore, it also falls on that line.

the polygon is 15 sided.
I think the correct answer to this question would be 2!
