    Are you saying there's a linear function that goes through (-2, 4) and (10, 15)?

    Do you know how to work out the gradient? Do you know how to use this and a point to find the y-intercept?

    Are you asking for the following?

    Find all functions

    f : IR -> IR , f ( x ) = m x + b

    such that

    f ( [ - 2 , 4 ] ) = ( [ 10 , 15 ] )
