Find the slope of the line passing through the points (8,-4) and (-7, -4).
Tju [1.3M]

Answer:

Step-by-step explanation:

slope=m=(Y2-Y1)/(X2-X1)

As given values

take,   (X1,Y1)=(-7,-4)

          (X2-Y2)=(8,8)

hence   X1=-7  ,  Y1= -4   ,  X2=8  , Y2= 8

putt the values in the above equation of slope we get ,

m=(8-(-4))/(8-(-7)

m=12/15    Ans
