Question

2x-y-2=0,4x-y-4=0 solve graphically

Answer 1

Here we are given two equation

Equation 1: 2x-y-2=0

Equation 2: 4x-y-4=0

Now in order to graph them we use table method here.

In table method we find two coordinates for each equation.

Equation 1: 2x-y-2=0

Let us say y=0, plugging this value in equation,

2x-0-2=0

2x=2

x=1

we get x=1

So our first point is (1,0)

Again say y=2,

2x-2-2=0

x=2

our second point is (2,2)

Same way for second equation:

Equation 2: 4x-y-4=0

Say y=0, so x=1

for y= 4, x= 2

Two points will be (1,0) and (2,4).

Now we graph them and see the point of intersection, that will be our solution.

As seen from the graph the point of intersection is at (1,0).

Answer: x=1 and y=0
