The slope is #3#.

To find the slope given two points, we use the formula #"rise"/"run"#, or #(y_2-y_1)/(x_2-x_1)#.

Plug in the given points into the formula:
#(5-(-1))/(-1-(-3)) = 6/2 = 3#

Therefore, the slope is #3#.

Hope this helps!

#3#

Slope is given by the formula

#(Deltay)/(Deltax)#

where the Greek letter #Delta# (Delta) is shorthand for change in.

We just see how much our #y# changes by, and divide it by how much our #x# changes by.

#y# goes from #-1# to #5#, which represents a #Deltay# of #6#.

#x# goes from #-3# to #-1#, which represents a #Deltax# of #2#.

Dividing the two, as our slope, we get

#3#

Hope this helps!
