solve graphically the following system of equations`2x-y-2=0` `4x-6y-10=0`

Answer» Equation of line 1,
`2x-y =2`
When `y = 0`, then `x = 1`.
When `x = 0`,then, ` y = -2`.
So, we can draw a line joining points `(1,0) and (0,-2)` to draw equation of line 1.
Equation of line 2,
`4x-6y =10`
When `y = 0`, then `x = 5/2`.
When `x = 0`,then, ` y = -5/3`.
So, we can draw a line joining points `(5/2,0) and (0,-5/3)` to draw equation of line 2.
When we draw these lines on the graph, we find the intersection point is `(1/4,-3/2)`, which is the required solution.
So, ` x = 1/4 and y = -3/2`
