Answer:
Step-by-step explanation:
they have given you three points P1 , P2 and P3. We only need two of them, any two will work
P1= (x1, y1) = (-1,8)
P2=(x2,y2) = (3,-4)
now use the slope formula to find the slope , use the variable 'm' for slope since that a very commonly used variable letter for slope
m = ( y2 - y1 ) / ( x2 - x1 )
m = (-4 - 8 ) / ( 3 - (-1) )
m = (-12) / 3 + 1 )
m = -12 / 4
m = - 3
there is your slope, got it? send a note if you have other questions :)
