To graph:the two lines appear to intersect each other with the help of given information.
Answer to Problem 36PPE
The lines intersect each other.
Explanation of Solution
Given information:
Given table:
X | Y |
-2 | 9 |
-1 | 7 |
0 | 5 |
1 | 3 |
2 | 1 |
X | Y |
-2 | -18 |
-1 | -14 |
0 | -10 |
1 | -6 |
2 | -2 |
Calculation:
Consider the table provided for the two lines in the textbook.
Let the slope
Now solve to find the values of
Use the first table,
Put the points (-2,9) and (-1,7) from first table in
Hence,
After solving the above equations,
Use the second table,
Put the points
Hence,
After solving the above equations,
Thus, the two equations become as follows,
Plot the above lines with the use of table provided in textbook,
From the above figure it is that the lines intersect each other.
