Answer:
The slope of the x axis is 0.
Step-by-step explanation:
You can find this by picking any two points on the line and using the slope formula. For this purpose, we'll use (3, 0) and (7, 0)
m(slope) = (y2 - y1)/(x2 - x1)
m = (0 - 0)/(7 - 3)
m = 0 /4
m = 0
And this will be the same for any points that you choose on the axis.
