a. 
b. 
Step-by-step explanation:
Given
The data in the table
Solving (a): The coordinate that represents the unit rate
The unit rate is when its 1 pound
This is so because the unit rate is dollars per pounds.
<em>Hence, the coordinate is </em><em></em>
Solving (b): Equation of the graph
First, we calculate the slope (m)
Where:
The equation is then calculated as thus:
This gives:
Make y the subject
<em>Hence, the equation of the graph is: </em><em></em>
Answer:
k = 2
Step-by-step explanation:
5k = 6k + 4 - 6
We can simplify this by solving 4 - 6 (replacing it with -2 !)
5k = 6k - 2
Now we can subtract 5k from both sides.
0 = k - 2
Finally, we can add 2 to both sides. This gets rid of the negative 2 on the right.
2 = k
Just reversing it...
k = 2
Answer: k = 2
