Grade 10 Using coordinate Geometry

Exercise1 a. Find the distance between A and B.

Exercise1 b. Find the midpoint of AB.

Exercise1 a. Find the gradient of the interval joining A and B.

Distance AB Midpoint of A and B Gradient of the line AB

Exercise2 a. What is the equation of AB ? OC is perpendicular to AB The y-intercept of AB is: The Gradient of AB is: So, the equation of AB is: y =

Exercise2 a. What is the gradient of OC ? OC is perpendicular to AB The equation of OC is: y = b. What is the equation of OC ?
