You use the distance formula.
The formula is the square root of: (x2-x1)^2 plus (y2-y1)^2
The length of a line segment is called the distance. To find the distance, you need to know the coordinate of its endpoints given as (x1, y1) and (x2, y2) and the distance formula.
First find the length between the midsegment point and coordinate B. The difference between 0 and -3 is 3. Thus, half the line is 3. So, to get to A, we have to go 3 in the other direction. -3 and 3 more would make Coordinate A land on (-6,2)
To calculate the x-coordinate of the midpoint of a horizontal segment, you simply take the sum of x-coordinate of the endpoints of the horizontal segment and divide this by two. An example is if one is given endpoints with th x and y coordinates 2,3 and 5,6. To find the midpoint of the x-coordinates add 2 and 5 and divide this by 2, or 7/2.
segment pj pn is 8x+3 NH IS 9X-6 AND HJ IS 5X+5
The formula is the square root of: (x2-x1)^2 plus (y2-y1)^2
The length of a line between two points, (x1,y1) and (x2,y2) on a Cartesian Plane is given by the formula: length = square root [ (x2 - x1)2 + (y2 - y1)2 ]
The length of a line segment is called the distance. To find the distance, you need to know the coordinate of its endpoints given as (x1, y1) and (x2, y2) and the distance formula.
Vertical.
The 'x' coordinate of the midpoint is the average of the 'x' coordinates of the segment's ends. The 'y' coordinate of the midpoint is the average of the 'y' coordinates of the segment's ends.
I think that you draw a square from that line, and find the area of that square.
It means to put the coordinates you were given on the coordinate plane. Ex. (-3,2) you find it the on the coordinate plane and then you plot it or graph it

Compare the distance to a known length. Measure. If you know the coordinates of the two dots in an orthogonal coordinate system, use Pythagoras' theorem to find the distance. Say point 1 has coordinate (Ax,By) and point 2 has coordinate (Cx,Dy) then the distance between 1 and 2 is the square root of ((C-A)2 + (D-B)2))
well, you find the two cooridinates on the plane and then graph them! KINDA EASY!
double the length
you count the number of boxes IN the shape.
