How do I answer these questions?

Give me the equations of two lines that have the same slope but are not parallel.

Can someone show me step by step how to do this?

The temperature of a chemical solution is originally 21 ? c . a chemist heats the solution at a constant rate, and the temperature of the solution 75 ? c after 1212 12 minutes of heating. the temperature, tt t , of the solution in ? c is a function of x , the heating time in minutes. write the function's formula.
