What is the slope of the line passing through the following points: # (-1,3) ,(-3, -6) #?

1 Answer

First of all you need the formula of the slope which is
#(y_2-y_1)/(x_2-x_1)#
Then use these values and place them in their designated places
#y_2= -6#
#y_1=3#
#x_2=-3#
#x_1=-1#
so: #(-6-3)/(-3-(-1))#

#(-9)/(-3+1)# Remember #(-)*(-)# is #(+)#

#(-9)/(-2)#

so gradient is #4.5#
remember to cancel out the #-# sign
