in this case the slope is -1/3, the negative part simply means the slope is going down from left-to-right, as it'd be the case in a waterslide.
Answer:
Vertical change is 2 feet.
Step-by-step explanation:
The equation of the line is
This equation can be rewritten as :
If a rider coming down this slide has a horizontal change of 6 feet, then their x-coordinate will change by 6.
This means that their new x-coordinate will be 6.
We can now plug this value of x into the equation for y to find their new y-coordinate.
Adding 4 on both sides
Therefore, the value of their vertical change is 2 feet.
In other words, if a rider starts at the point (0, 4) on the graph, and they move 6 units to the right, they will end up at the point (6, 2).
The vertical change is 4 - 2 = 2 feet.
ANSWER:
The temperature in Small ville, six hours ago was 13 degrees.
SOLUTION:
Given, current temperature in Smallville is 20 degrees.
And this is 6 degrees less than twice the temperature that it was six hours ago.
We need to find what was the temperature six hours ago.
Let the temperature six hours ago be x.
Then, 2x - 6 = 20 [ according to the given information
2x = 20 + 6
2x = 26
x =
x = 13 degrees.
Temperature six hours ago was 13 degrees
Hence, the temperature in smallville , six hours ago was 13 degrees.
