[2] CAREER POINT CAREER POINT Ltd., CP Tower, IPIA, Road No.1, Kota (Raj. Given a straight line with equation coefficients as a, b & c(ax + by + c = 0), the task is to find the area of the triangle formed by the axes of co-ordinates and this straight line.. 5y = - 3x + 15. y = (-3/5) x + 3. m = - 3/5 is slope of line . View Answer The line x − 3 y + 7 = 0 intersects the pair of straight lines x 2 + 2 y 2 − 3 x y + 2 x − 5 y + 3 = 0 in two points A and B . (C.B.S.E. Question 12. x – 2y = 5 3x – 6y = 15 Solution: x – 2y = 5 x = 5 + 2y Substituting some different values of y, we get corresponding values of x as shown below: Now plot these points on the graph and join them 3x – 6y = 15 => 3x = 15 + 6y x = \(\frac { 15 + … A circle is drawn through A, B and the origin.
