Question

solve graphically:y=2x-2 and y=4x-4​

Answer 1

Step-by-step explanation:

=2x-2;y=4x-4

Solution :

{y,x} = {0,1}

System of Linear Equations entered :

[1] y - 2x = -2

[2] y - 4x = -4

Graphic Representation of the Equations :

-2x + y = -2 -4x + y = -4

Solve by Substitution :

// Solve equation [2] for the variable y

[2] y = 4x - 4

// Plug this in for variable y in equation [1]

[1] (4x-4) - 2x = -2

[1] 2x = 2

// Solve equation [1] for the variable x

[1] 2x = 2

[1] x = 1

// By now we know this much :

y = 4x-4

x = 1

// Use the x value to solve for y

y = 4(1)-4 = 0

Solution :

{y,x} = {0,1}
