60? idk really srsly lalalalalallala
It’s hard to completely answer without a graph or coordinates, but I do believe that point slope form is y-y1=m(x-x1). Plug in your slope for m. After that, plug in your x coordinate in the appropriate place as well as your y coordinate. Solve from there
Do you want to express this in the terms of anything?
