Math Problem Statement

(-2,4) (1,1)

Solution

The given points are (2,4)(-2, 4) and (1,1)(1, 1). Let's calculate the slope, distance, and the midpoint of the line segment connecting these two points.

1. Slope (mm) Calculation

The formula for the slope is: m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1} Substitute the given points: m=141(2)=33=1m = \frac{1 - 4}{1 - (-2)} = \frac{-3}{3} = -1 Slope: 1-1


2. Distance (dd) Calculation

The formula for the distance is: d=(x2x1)2+(y2y1)2d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} Substitute the given points: d=(1(2))2+(14)2=(3)2+(3)2=9+9=18=32d = \sqrt{(1 - (-2))^2 + (1 - 4)^2} = \sqrt{(3)^2 + (-3)^2} = \sqrt{9 + 9} = \sqrt{18} = 3\sqrt{2} Distance: 323\sqrt{2} (approximately 4.244.24)


3. Midpoint Calculation

The formula for the midpoint is: Midpoint=(x1+x22,y1+y22)\text{Midpoint} = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right) Substitute the given points: Midpoint=(2+12,4+12)=(12,52)\text{Midpoint} = \left( \frac{-2 + 1}{2}, \frac{4 + 1}{2} \right) = \left( \frac{-1}{2}, \frac{5}{2} \right) Midpoint: (12,52)\left( -\frac{1}{2}, \frac{5}{2} \right)


Final Results:

  1. Slope: 1-1
  2. Distance: 323\sqrt{2}
  3. Midpoint: (12,52)\left( -\frac{1}{2}, \frac{5}{2} \right)

Here are some follow-up questions for exploration:

  1. What is the equation of the line passing through these points?
  2. How does changing one coordinate affect the slope and distance?
  3. Can the points form a right triangle with the origin? Why or why not?
  4. What is the equation of a circle with these two points as endpoints of a diameter?
  5. How would you graph these points and calculate the results visually?

Tip: Always visualize the points on a graph to better understand relationships like slope and distance.
