You can
put this solution on YOUR website!Find the slope of the line passing through the points (2, 2) and (4, 2).
a)0
b)1
c)2
d)Undefined
Notice that both the y's are 2, if you were to plot the two points and connect the points, you would have a horizontal line. The slope of horizontal lines is 0.
If you don't know that, the general way that students find the slope between two points is by using the slope formula:

, where m=slope and (x1,y1) and (x2,y2) are the two given points.
(x1,y1)=(2,2) and (x2,y2)=(4,2)

that is (a) in your multiple choice.
Happy Calculating!!!
