WORKBOOK
Ex: d 1: 2x – y + 3 = 0 and d 2: ax + 3y – 2 = 0. If the lines d 1 and d 2 are perpendicular then find
a .
Ex: Find the y-intercept of the line passing through the point A(2, 0) and parallel to d : 2x-y+1=0.
Ex: What is the equation for the perpendicular bisector of the line segment between points A(–2,
1) and B(2, 3)
Ex: The lines d and e are perpendicular as shown in the
figure. Find the y-intercept of the line d.
RELATIVE POSITIONS OF TWO LINES
Let : ax+by+c = 0 and : dx+ey+f = 0 be any two lines (Which means
that they are co-planar) .
