Question 573812
logically
for slope of point to point starting at (-1,9) from plots you go up 12 and to the right 10
12/10 would be a slope but if u divide both top and bottom by 2 that would make it exactly halfway 12/2=6 10/2=5 so slope is also 6/5
go back to first point -1,-9 then go up 6 and right 5 to get (4,-4) as mid point
