What is the slope of the line that goes through #(1,2)# and #(-3,2)#?

1 Answer

#0#

Explanation:

To calculate the slope of a line when given two points is simple. Take one y-coordinate and subtract it from the other y-coordinate. then divide by one x-coordinate minus the other x-coordinate.
#(y_2-y_1)/(x_2-x_1)#
The / indicates a fraction bar.
So in this case, #(2-2)/(1 - (-3))#
Which turns into, #0/4#
And #0# divided by anything equals zero
So the slope is #0#
