Q4 of 169 Page 656

If the slope of the line joining the points A(x, 2) and B(6, -8) is , find the value of x.

If a line passing through then slope of the line is given by .

Given points are A(x,2) and B(6,-8), and the slope is

⇒-40 = -30+5x
⇒5x = -10
⇒x = -2

Find the inclination of a line whose slope is

(i)

(iii) 1

(iv) -1

(v)

Find the slope of a line which passes through the points

(i) (0, 0) and (4, -2)

(ii) (0, -3) and (2, 1)

(iii) (2, 5) and (-4, -4)

(iv) (-2, 3) and (4, -6)

Show that the line through the points (5, 6) and (2, 3) is parallel to the line through the points (9, -2) and (6, -5)

Find the value of x so that the line through (3, x) and (2, 7) is parallel to the line through (-1, 4) and (0, 6).
