INSTRUCTIONS:
1 . Input two lines in eather general or slope - intercept form.
2 . You can input integers (10), decimals (10.2), fractions (10/3) and Square Roots - (use letter 'r' as a square root symbol).
Example: $ \text{ 2r3 } = 2 \cdot \sqrt{3}$
3 . The examples of valid lines are $y = 2x - 3$ , $\frac{1}{3}x + 2y = 4$ and $\sqrt{2}x + \sqrt{3}y = 1$
