Thank you for the opportunity to help you with your question!

I am assuming that you want to write an equation given the slope and a point on the line? You can use slope-intercept form y = mx + b, where m is your slope and b is your y-intercept. First find your slope if you need to using your change in y/change in x. When you have the slope and the point given, substitute the slope and the solution into the slope intercept formula and solve for b. Once you have "b", you can write the equation by substituting in the slope and the b in the y=mx+b formula.

Please let me know if you need any clarification. I'm always happy to answer your questions.
