Answer:
The point for the given linear equations is ( ,
)
Step-by-step explanation:
Given as :
The two linear equations are
First equation
y =
x + 5
Or, y +
x + 5 = 0
Taking LCM we get
y + x + 10 = 0 .......1
Second equation
y = 2 x + 2 ........2
Now solving both equation
Putting the value of y from eq 2 into eq 1
(2 x + 2) + x + 10 = 0
Or, 3 x + 12 = 10
Or, 3 x = 10 - 12
Or, 3 x = - 2
∴ x =
Now putting the value of x into eq 2
∵ y = 2 x + 2
Or, y = 2 × + 2
Or, y = + 2
Or, y =
∴ y =
So, The points are (x , y ) = ( ,
)
Now, plotting the points on x-y coordinate graph
Hence, The point for the given linear equations is ( ,
