Question

The straight line $2x + 3y + 4 = 0$ touches the x-axis at:

• A. -2.0
• B. +2.0
• C. -1.0
• D. +1.0

Hint:

X-intercept $\rightarrow$ set $y=0$. Y-intercept $\rightarrow$ set $x=0$.

Answer 1

The Correct Option is A

Step 1: Concept
A line touches the x-axis where the y-coordinate is zero ($y = 0$).

Step 2: Meaning
Substitute $y = 0$ into the equation to find the x-intercept.

Step 3: Analysis
$2x + 3(0) + 4 = 0 \Rightarrow 2x + 4 = 0 \Rightarrow 2x = -4$.

Step 4: Conclusion
$x = -2$. The line touches the x-axis at -2.0. Final Answer: (A)
