Find the equation of a straight line which cuts an intercept – 2 units from Y-axis and being equally inclined to the axis.
The vertices of a ΔABC are A(3, 8), B(–1, 2) and C(6, –6). Find:
(i) Slope of BC
(ii) Equation of a line perpendicular to BC and passing through A.
In the adjoining figure, write
(i) The coordinates of A, B and C.
(ii) The equation of the line through A and | | to BC.
Find the value of ‘a’ for which the following points A (a, 3), B (2, 1) and C (5, a) are collinear. Hence find the equation of the line.
PQ is straight line of 13 units. If P has coordinate (2, 5) and Q has coordinate (x, – 7) find the possible values of x.
Find the equation of a line which is inclined to x axis at an angle of 60° and its y – intercept = 2.
