You've had a dozen or so exercises done for you. Have you studied and learned from them, or are you still not showing any work because you're just copying the answers into your homework?
Please note that most tutors will not do your assignment for you, so it would be productive if you started showing some effort of your own. For instance, you've been shown how to work with slope. So you've studied that, memorized the "slope" formula, plugged these points into that formula, set the result equal to the required value, and... then what?
Please provide full details. Thank you.
