1.	Find equation of the line perpendicular to the line x – 7y + 5 = 0 and having x intercept 3.
Answer» The given equation of line is x – 7y + 5 = 0. or, y = 1/7 X + 5/7 which is of the form y = mx + c ∴Slope of the given line = 1/7 The slope of the line perpendicular to the line having a slope of 1/7 is m = - 1/(1/7) = -7 The equation of the line with slope –7 and x-intercept 3 is given by y = m (x – d) ⇒ y = –7 (x – 3) ⇒ y = –7x + 21 ⇒ 7x + y = 21
