Line ab and bc for a right angle at point b. if a(-3,4) and b(4,4) what is the equation of line bc?

 The required equation of line BC is

Step-by-step explanation:  As shown in the attached figure, lines AB and BC meet at right angle at the point B. The co-ordinates of point A and B are (-3, 4) and B(4, 4).

We are to find the equation of line BC.

We know that the slope of a line passing through the points (a, b) and (c, d) is given by

So, the slope of the line AB will be

Therefore, the equation of the line AB is

Since y = constant is the equation of a line parallel to X-axis, so its perpendicular line will be parallel to Y-axis.

So, its equation will be of the form

x = constant.

Since the line BC is perpendicular to AB passing through the point (4, 4), so we must have

Thus, the required equation of line BC is

1,8,15,22,29,36,43,50
