The slope of a line passing through two points is the ratio between the difference of the y coordinates and the difference of the x coordinates. In formulas, you have
If you plug your values, you have
which is undefined.
In fact, since the two points share the same x coordinate, the segment AB is vertical, and the slope is not defined for vertical lines.
Answer:
40mph
Step-by-step explanation:
(60mph+20mph)/2
40
Answer:
100
Step-by-step explanation:
The Richter scale is a logarithmic scale, so the ratio of intensities is ...
(10^5)/(10^3) = 10^(5-3) = 10^2 = 100
The latter quake is 100 times as intense as the former one.
