1.
5x2 + 4y = 6
2.
x-y=-9
3.
+8/7 = 10
y - 2x - 15 = 0 5.
Things to remember in identifying linear equation in two variables.
It has two variables.
There is NO more than one variable in each term.
The exponent of the variable in each term is 1 (or the degree of the equation is 1)
There is NO variable in the denominator.
There is NO variable inside radical sign.
Generally, it is written in the form Ax + By=C.​

Answer:

1.Yes

2.yes

3.yes

4.no

5.yes

Step-by-step explanation:

The standard form for linear equations in two vaiables 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.
