Answer:
A. {(1, 6.7), (2, 6.4), (3, 6.1)}
Step-by-step explanation:
The watering can dispenses water at a rate of 0.3 gallon per minute and the original volume of water in the can was 7 gallons.
Let y represent the volume of water in the can in gallons
Let x represent time in minutes
f(x) = y = 7 – 0.3(x)
When x = 1,
y = 7 – 0.3(1)
= 7 – 0.3
= 6.7
The pair will be (1, 6.7)
When x = 2,
y = 7 – 0.3(2)
= 7 – 0.6
= 6.4
The pair will be (2, 6.4)
When x = 3,
y = 7 – 0.3(3)
= 7 – 0.9
= 6.1
The pair will be (3, 6.1)
The set of ordered pairs shows the volume of water in the can in gallons (y) as a function of time in minutes (x) from the first minute after the can starts dispensing water is {(1, 6.7), (2, 6.4), (3, 6.1)}
Answer:
Step-by-step explanation:
First, we will find the midpoint for the x - coordinate first.
Midpoint (x) = 
Now we will find the midpoint for the y - coordinate.
Midpoint (y) = 
Therefore from these 2 values we know that the midpoint of this 2 points is (-3.5,-0.5)
Answer:
(7.5 , 5.5)
Step-by-step explanation:
The midpoint is halfway between the two end points:
Its x value is halfway between the two x values
Its y value is halfway between the two y values
To calculate it:
Add both "x" coordinates, divide by 2
Add both "y" coordinates, divide by 2

Answer:
y = 1x - 5
Step-by-step explanation:
We will use the slope equation for this: y = mx + b
y is our output/answer
m is our slope, or the rate of change
x is our x coordinate. For example, in (3,2) x would be 3.
b is our y intercept, or where the line passes through the y axis.
Knowing this, we can fill out the blanks.
when we look at one point on the grid, and then find the next closest number from the point we chose, we can see that the slope is 1 so we now have: y = 1x + b
to find b, we find where the line passes over the y axis which on our grid is -5. Normally we would write: y = 1x + 5 Since we have a negative 5 or -5, we will change the + to a -
This means we write y = 1x -5.
I hope this helps you and have a great day :D
