you can use this formula:
m is the slope of a line
and (x1,y1), (x2,y2) are two points on the line
then: m=(y2-y1)/(x2-x1)
for your case y2=2 , y1=4 , x2=-3, x1=-7
then
m=(2-4)/(-3+7)=-2/4 = -1/2.
The slope is -1/2= -0.5

slope = (y2 - y1) / (x2 - x1)
so its (2 - 4) / (-3 - (-7)
= -2 / (-3 + 7)
= -2 / 4
= - 1/2
The dude above me forgot his signs!!
