Answer:
The coordinates of N are (-1,-6)
Step-by-step explanation:
M is the midpoint of AN
A(-7,4) and M(-4,-1)
The distance AM is given by (-4--7,-1 - 4) = (3,-5)
Since AM = MN;
N = M(-4,-1) + (3,-5)
N = (-4 + 3,-1 + -5)
This gives the coordinates of N to be;
N(-1,-6)
It cannot be expressed as a mixed fraction. Dividing 36 by 4 gives 9 which is a whole number.
A line segment is a line between its endpoints.
Looking at the data it looks like a line. So the answer will be in y+mx+b format.
Knowing it is a line eliminates answers b and c.
looking at options a is says it starts at about .1 when x is zero. We can see this looks pretty close as the left-most dot is below 1 already.
The slope on a is 1/2--> increasing 1 vertically for every 2 horizontally. The pattern mostly follows that rule.
Therefore a (y=1/2x+.1) would be the correct answer
