Answer:
Solution (4,3)
Step-by-step explanation:
System of Equations
It's given the graph of the function
y = 7 - x
a) It's required to plot the graph the function
y = x - 1
Some points of the graph are:
x=2 => y = 2 - 1 = 1. Point (2,1)
x=3 => y = 3 - 1 = 2. Point (3,2)
x=4 => y = 4 - 1 = 3. Point (4,3)
x=5 => y = 5 - 1 = 4. Point (5,4)
x=6 => y = 6 - 1 = 5. Point (6,5)
The graph is shown in the image attached below.
2)
The simultaneous graphs give the intersection point (4,3), which is the solution of the system of equations:
y = 7 - x
y = x - 1
