The point of intersection of the line y = ax + b with X – axis is �

1.	The point of intersection of the line y = ax + b with X – axis is …………………A) (- b/a,0)B) ( b/a,0)C) (0, b/a,)D) (0, - b/a,)
Answer» Correct option is (A) (- b/a, 0) Equation of line X-axis is y = 0. \(\therefore\) For point of intersection of line y = ax+b with X-axis (i.e., y = 0 line), we have ax + b = 0 \(\Rightarrow\) \(x=\frac{-b}{a}\) Hence, point of intersection is \(\left(\frac{-b}{a},0\right).\) Correct option is A) (- b/a,0)

The point of intersection of the line y = ax + b with X – axis is …………………A) (- b/a,0)B) ( b/a,0)C) (0, b/a,)D) (0, - b/a,)

Answer»

Correct option is (A) (- b/a, 0)

Equation of line X-axis is y = 0.

\(\therefore\) For point of intersection of line y = ax+b with X-axis (i.e., y = 0 line), we have

ax + b = 0

\(\Rightarrow\) \(x=\frac{-b}{a}\)

Hence, point of intersection is \(\left(\frac{-b}{a},0\right).\)

Correct option is A) (- b/a,0)
