Answer: The required x-co-ordinate of the point of intersection of two lines is
Step-by-step explanation: Given that two perpendicular lines have opposite y-intercept and the equation of one of the lines is
We are to express the x-coordinate of the intersection point of the lines in terms of m and b.
Let the slope and y-intercept of the other line be s and c respectively.
Since the product of the slopes of two perpendicular lines is -1 and -b is the opposite of b, so we have
and c = -b.
That is, the equation of the other line is
Comparing the equations of both the lines, we get
Thus, the required x-co-ordinate of the point of intersection of two lines is
