Equation of Straight Line Between Two Points
- Godfrey Almeida
Find the equation of the straight line that passes through the points (1, 2) and (4, 6). Give your answer in the form .
Plot the points (2, 6) and (6, 2). What is the gradient of this line?
In the previous question, the coordinates were a reflection of each other. Which line was the mirror line?
Can you find other coordinate pairs which have this same property? Write some down. Does this always happen? Can you prove your result?
Draw the line . Change one aspect so that the equation 1st, 2nd and 4th quadrant. How many different ways can you find to achieve this?
