Answer:
The value of x , y coordinate is ( 1, )
and Plotting the points on graph
Step-by-step explanation:
Given as :
The system of equation is
y = x - 1
The equation can be written as
4 y = x - 4
Or, 4 y - x + 4 = 0 ........1
y = - x -
The equation can be written as
4 y + 2 x + 1 = 0 ..........2
Solving the equation
i.e ( x - 4 ) + 2 x + 1 = 0
or, 3 x - 4 + 1 = 0
or, 3 x = - 1 + 4
∴ 3 x = 3
I.e x = 1
Put the value of x in eq 1
So, 4 y - x + 4 = 0
or, 4 y - 1 + 4 = 0
or, 4 y + 3 = 0
or, 4 y = - 3
∴ y =
So, The value of x , y coordinate is ( x ,y ) = ( 1 , )
Hence The value of x , y coordinate is ( 1, )
