CONCEPT PREVIEW Fill in the blank(s) to correctly complete each sentence. The midpoint of the segment joining (0, 0) and (4, 4) is ________.

Verified step by step guidance
1
Recall that the midpoint of a segment joining two points \((x_1, y_1)\) and \((x_2, y_2)\) is given by the formula: \[\left( \frac{\,x_1 + x_2}{2}, \frac{\,y_1 + y_2}{2} \right)\]
Identify the coordinates of the two given points: \((0, 0)\) and \((4, 4)\). Here, \(x_1 = 0\), \(y_1 = 0\), \(x_2 = 4\), and \(y_2 = 4\).
Substitute these values into the midpoint formula: \[\left( \frac{0 + 4}{2}, \frac{0 + 4}{2} \right)\]
Simplify the expressions inside the parentheses by performing the addition and division: \[\left( \frac{4}{2}, \frac{4}{2} \right)\]
Express the simplified midpoint coordinates as a point: \[\left( 2, 2 \right)\]

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Midpoint Formula

The midpoint of a line segment between two points (x₁, y₁) and (x₂, y₂) is found by averaging their coordinates: ((x₁ + x₂)/2, (y₁ + y₂)/2). This gives the exact center point of the segment.
