What is the slope of the line that passes through the points (5,−4) and (7, -4) ?Write your answer in simplest form.
1 answer:
Answer:
Undefined
Step-by-step explanation:
☆ (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate.
Slope of the line
Thus, the slope of the line is undefined.
(Since 2 cannot be divided by zero)
Notice that the two coordinates have the same y- coordinate of -4. This means that the line is a vertical line. Vertical lines have undefined slopes.

The conversions factors needed are 1 mile= 5280 feet and 1 hour = 3600 seconds, speed in ft/s = 14.67 ft/s
<u>Solution: </u>
Given, A runner is running 10 miles per hour.
We have to find what conversion factors should be used to convert 10 mi/hr to ft/s?
Now, speed of runner = 10 miles per hour.
But we need the units to be in ft / s.
Then, conversion factors are miles to feet and hours to seconds.
Now, miles to feet ⇒ 1 mile = 5280 feet.
Now, hours to seconds ⇒ 1 hour = 3600 seconds
Hence, the conversions needed are 1 mile = 5280 feet and 1 hour = 3600 seconds, speed in ft/s = 14.67 ft/s
