Math Problem Statement

Find the midpoint of points A(-9,-7)and B(1,0) Graphically

Solution

To find the midpoint of points A(9,7)A(-9, -7) and B(1,0)B(1, 0) graphically, we first calculate the midpoint using the midpoint formula:

Midpoint=(x1+x22,y1+y22)\text{Midpoint} = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right)

For points A(9,7)A(-9, -7) and B(1,0)B(1, 0):

Midpoint=(9+12,7+02)=(82,72)=(4,3.5)\text{Midpoint} = \left( \frac{-9 + 1}{2}, \frac{-7 + 0}{2} \right) = \left( \frac{-8}{2}, \frac{-7}{2} \right) = \left( -4, -3.5 \right)

Now, let's graph this:

  1. Plot the points A(9,7)A(-9, -7) and B(1,0)B(1, 0) on a coordinate plane.
  2. Draw a line connecting points AA and BB.
  3. The midpoint (4,3.5)(-4, -3.5) lies exactly halfway along this line.

This point is the visual center of the line segment AB.
