Graphing the system of equations is shown in figure attached.
Solution set is (2,-4). The lines will intersect at (2,-4)
Step-by-step explanation:
We need to graph the system of equations.
First we will find value of x and y
Let:
Add eq(1) and eq(2)
Putting value of x in eq(1) and finding y
So, y=-4

Answer:
Table 3 has a greater y intercept
Step-by-step explanation:
See attachment (1) & (2) for graph and tables
First, we have to determine the y intercept of the graph
The y intercept of any graph or table is the corresponding value of a point where
In the attached graph.
when
So:
Next, we determine the y intercept of each table.
Recall that: The y intercept of any graph or table is the corresponding value of a point where
For table 1:
For table 2:
For table 3:
By comparison, the y intercepts of tables (1) & (2) are less than the y intercept of the graph because: 3 and 2 are less than 4
However, the y intercept of table 3 is greater than the y intercept of the graph because 5 is greater than 4.
<em>Hence, table 3 has a greater y intercept</em>
