Question

liner Equation formula​

Answer 1

Step-by-step explanation:

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.

Answer 2

According to Heron's formula the area of triangle $= \sqrt{s( s- a)( s-b )( s- c)}$

Where, $s(semiperimeter) = \frac{a + b + c}{2}$

And, ‘a’, ‘b’, and ‘c’ are sides of triangle.
