### How long will a line from 1,4 to 4,4 be?

• A.

Four units

• B.

Eight Units

• C.

Can't tell from those coordinates

• D.

Three Units

D. Three Units
Explanation
The length of a line can be calculated using the distance formula, which states that the distance between two points (x1, y1) and (x2, y2) is equal to the square root of the difference in x-coordinates squared plus the difference in y-coordinates squared. In this case, the x-coordinates are 1 and 4, and the y-coordinates are both 4. Plugging these values into the formula, we get the square root of (4-1)^2 + (4-4)^2, which simplifies to the square root of 9, or 3. Therefore, the length of the line from (1,4) to (4,4) is three units.
