Question

Angle Between Two Straight Lines

1]. Show that the line 2x+4y=3 is perpendicular to the line passing through the point (7,3) and
(0,-11).

2]. Show that the line passing through the points (2,2)and (5,4)is perpendicular to the line passing through the point (-4,4) and (0,-2)

3]. Show that the line joining point (0,0) and (2,3) is parallel to the line joining point (2,-2) and (6,4)

4]. If the line passing through (2,-5) and (7, a)
is parallel to the line given by the equation
y+3x+8=0, then find the value of a.
