Math Problem Statement

Calculate the distance between the two points (-4,7) and (-2,5)

Solution

To calculate the distance between the two points (4,7)(-4, 7) and (2,5)(-2, 5), you can use the distance formula:

Distance=(x2x1)2+(y2y1)2\text{Distance} = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

Given points: (x1,y1)=(4,7)(x_1, y_1) = (-4, 7) (x2,y2)=(2,5)(x_2, y_2) = (-2, 5)

Substitute the values into the formula:

Distance=((2)(4))2+(57)2\text{Distance} = \sqrt{((-2) - (-4))^2 + (5 - 7)^2}

Simplify the expressions:

Distance=(2)2+(2)2\text{Distance} = \sqrt{(2)^2 + (-2)^2} Distance=4+4=8\text{Distance} = \sqrt{4 + 4} = \sqrt{8}

Simplify the square root:

Distance=8=222.83\text{Distance} = \sqrt{8} = 2\sqrt{2} \approx 2.83

So, the distance between the points (4,7)(-4, 7) and (2,5)(-2, 5) is 222\sqrt{2}, which is approximately 2.83 units.

  5. What is the length of the line segment connecting the points (4,7)(-4, 7) and (2,5)(-2, 5) in a coordinate plane?

Tip: Remember that the distance between two points in a coordinate plane is always a positive number, as it represents a physical length.
