Answer:
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "c" is the y-intercept.
By definition:
1. If the lines of the System of equations are parallel (whrn they have the same slope), the system has No solutions.
2. If the they are the same exact line, the System of equations has Infinite solutions.
(A) Let's solve for "y" from the first equation:
You can notice that:
In order make that the System has No solutions, the slopes must be the same, but the y-intercept must not. Then, the values of "a" and "b" can be:
Substituting those values into the second equation and solving for "y", you get:
You can idenfity that:
Therefore, they are parallel.
(B) In order make that the System has Infinite solutions, the slopes and the y-intercepts of both equations must be the same. Then, the values of "a" and "b" can be:
If you substitute those values into the second equation and then you solve for "y", you get:
You can identify that:
Therefore, they are the same line.
Answer: Hence, our required model will be
Explanation:
Since we have given that
Luana bought a new phone and
For 3 months, the amount she paid = $175
For 6 months, the amount she paid = $295
Now, we have to model an equation ,
Here, let cost be 'C' and
Let number of months be 'm'.
So, we will use the "equation of line" i.e. for two point slope form :
Here y represented by 'C' and x represented by 'm'
So,
Hence, our required model will be
