Answer: B
Step-by-step explanation: divide 75 by 25 to find how many feet you travel in 1 second (75/25=3) then you take 3 times 10 to see how many feet you travel in 10 seconds (3x10=30).
To determine the position of a point
Answer:
the slope is -1/2 while the y-intercept is 80
Step-by-step explanation:
Let x be the time in minute and y be the water in the gallon.
From the question, the water flows at a rate of 1 gallon every 2 minutes, which implies that, the rate of change is the slope = 1/2.
The tank has a leak i.e The water flows out from the tank. Since the water flows out of the scope,it implies that the scope = -1/2. y- intercept is the initial amount of water in the tank which is 80.

Answer:
Step-by-step explanation:
The slope of a line can be seen as:
Rise over run is the change in the y values over the change in x values. For example, in this graph, you would start on one of the points given. From there, you would move up first. After moving up a certain number of spaces, you would move to the side until you reach the other point.
In the graph, you would move up until you are in line with one of the other points. Starting at (-4,5), move up one space, then to the left 4 spaces to reach the point (0,6). Using the spaces moved in the rise over run:
Therefore, the slope is .
This is true for any two points on the line.
:Done
*When you move up, the number will be positive . If you move down, the number will be negative . If you move left, the number will be positive . If you move right, the number will be negative . Keep this in mind. It is very important.
**Always <em>move along the y-axis first</em>, then move along the x-axis. If you do it the other way, the slope will be wrong.
