y1=5, x1=10 and y2=-7, x2=4
slope=%28y2-y1%29%2F%28x2-x1%29=%28-7-5%29%2F%284-10%29=-12%2F-6=2

Answer:The slope is given by formula:
m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29, where (x[2],y[2]) is the point (4,-7) and
(x[1], y[1]) is the point (10,5). After substituting we have:
m=%28-7-5%29%2F%284-10%29=
+m=-12%2F-6+=
m=2.
