The slope of this line is -2.

Explanation:

First of all, we begin with the definition of slope. Rise over run, or how a line progresses vertically in relation to how it moves horizontal

So, the formula to find the slope with any 2 coordinates is the vertical distance divided by the horizontal distance.
Or...
#(y_2-y_1)/(x_2-x_1)#

We subtract the first y value from the second to find the distance.
(#y_2-y_1#)
#(7-3)#
Do the same with the x value.
(#x_2-x_1#)
#(2-4)#
Now we have a rise of 4 as it goes up by 4
The run is -2 as it goes down by 2
#(y_2-y_1)/(x_2-x_1)#
#(7-3)/(4-2)#
Finally we have #4/-2#
By simplifying, the slope is -2.
Hope this helps.
