Find the equation of the line perpendicular to x–axis and having intercept – 2 on x–axis. |
|
Answer» Given: A line which is perpendicular to x–axis and having intercept –2 By using the formula, The equation of line: [y – y1 = m(x – x1)] We know that, the line is perpendicular to the x–axis, then x is 0 and y is –1. The slope of line is, m = y/x = -1/0 It is given that x–intercept is –2, so, y is 0. Coordinates of line are (x1, y1) = (–2, 0) The equation of line = y – y1 = m(x – x1) Now, substitute the values, we get y – 0 = (-1/0) (x – (– 2)) x + 2 = 0 ∴ The equation of line is x + 2 = 0 |
