WORKBOOK
Ex: Write the equation of the line that passes through the intersection point of 2x – y – 3 = 0 and
x + y = 0 lines and parallel to x-axis.
Ex: A(x, y), B(–3, 0), C(0, 1), D(0, –2) andd d A . If the slope angle of d 1 is 45° then
1 2
find x + y.
THE DISTANCE FROM A POINT TO A LINE
On the analytic plane, the distance of point A(x 1, y 1) to a line is d: ax + by + c = 0
Ex: Find the distance between the point P and line If
i) P(2,-3) , : 3x + 4y -7 = 0 ii) P(-1,5) , : 15x – 8y + 4 = 0
