Answer:
use this formula y2-y1 /x2-x1. I'll do the first one(15) for you but try to do the second one on your own. The slope for the equation is -1.
Step-by-step explanation:
step 1: plug in both of your points to the formula (1,-4)(6,3) so let's say our Y2 here is -4 and our Y1 is 3 and our X2 is 1 and our X1 is 6. We get -4-3 divided by 1+6 so -7 divided by is our slope or you can just write in simply as -1
