Answer: c) -5/2
hi! i'm the same person who answered your other question so i used a slope calculator again :)
but the equation is y2-y1 divided by x2-x1
so it's just from the coordinates (-2,3) and (4,-12) and the expression is
-12-3 divided by 4-(-2)
which is just -15 divided by 6 which you can divide by 3 for both parts of the fraction which is:
-5 divided by 2
i hope this helps :)
