Exercises: Linear functions and line equations

Determining the equation of a function.

A line passes through the points P1 and P2 . Determine the equation of the function f(x), the points of intersection and draw the graph for the following values:

  1. P1(2|1)P2(5|4)

  2. P1(3|2)P2(2|3)

  3. P1(2|3)P2(4|1)

  4. P1(4|1)P2(3|1)

  5. P1(3|92)P2(4|1)

  6. P1(4|2)P2(72|4)
