yup

that's fineI don't quite remember how to do this. In the end, I got Please correct me on this.

do as they say. change (x1, y1) to (x,y). simplify to get the equation in the slope-intercept form (y = mx + b, here, m is the slope and b is the y-intercept). you will be able to give them the info they require from this formThis is the part I thought was a brain teaser/tongue twister. What do you do here?

well, i gave you the hint on how to do C, so now you can try againI don't have the equation for C. yet, so I'll wait for help on that first.
