Question 40

Question. 40

Only one line can pass through a given point.

Answer:

false

Detailed Answer with Explanation:

Step 1: Think of a single dot. Call it point \(P\).

Step 2: Draw one line through \(P\). This is possible.

Step 3: Now tilt your ruler a little and draw another line that still passes through \(P\). This new line is different from the first one.

Step 4: Keep changing the tilt (the “slope”). Every different tilt gives a new, different line through the same point \(P\).

Step 5 (tiny algebra idea): If the point is \(P(a,b)\), then all lines through \(P\) can be written as:

\(y - b = m(x - a)\)

Pick a slope value:

\(m = 0:\quad y = b\)

\(m = 1:\quad y - b = x - a\)

\(m = -2:\quad y - b = -2(x - a)\)

Conclusion: There are infinitely many choices of \(m\), so infinitely many different lines pass through a single point. The statement is false.
