The Line Represented by x/4 + y/6 = 1 Intersects the X Axis and Y Axis Respectively at P and Q

Understanding the Problem

The given equation of the line is x/4 + y/6 = 1. We are asked to find the coordinates of the midpoint of the line segment PQ, where P and Q are the points at which the line intersects the x-axis and y-axis respectively.

Finding the Coordinates of P and Q

To find the coordinates of P and Q, we need to find the points at which the line intersects the x-axis and y-axis respectively.

When the line intersects the x-axis, the value of y is 0. Substituting y = 0 in the equation of the line, we get:

x/4 + 0/6 = 1

Simplifying the equation, we get:

x/4 = 1

Multiplying both sides of the equation by 4, we get:

x = 4

Therefore, the coordinates of P are (4, 0).

When the line intersects the y-axis, the value of x is 0. Substituting x = 0 in the equation of the line, we get:

0/4 + y/6 = 1

Simplifying the equation, we get:

y/6 = 1

Multiplying both sides of the equation by 6, we get:

y = 6

Therefore, the coordinates of Q are (0, 6).

Finding the Midpoint of PQ

The midpoint of a line segment is the point that divides the line segment into two equal parts. The coordinates of the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) are given by:

((x1 + x2)/2, (y1 + y2)/2)

In this case, the endpoints of the line segment PQ are (4, 0) and (0, 6). Therefore, the coordinates of the midpoint of PQ are:

((4 + 0)/2, (0 + 6)/2)

Simplifying the coordinates, we get:

(2, 3)

Therefore, the coordinates of the midpoint of the line segment PQ are (2, 3).

Conclusion

In this article, we have discussed how to find the coordinates of the midpoint of the line segment PQ, where P and Q are the points at which the line intersects the x-axis and y-axis respectively. We have used the equation of the line x/4 + y/6 = 1 to find the coordinates of P and Q, and then used the midpoint formula to find the coordinates of the midpoint of PQ. The coordinates of the midpoint of PQ are (2, 3).
