What do I graph? There is nothing there
(1)
since both equations express y in terms of x, equate the right sides
- 2x = - 4x + 10 ( subtract 4x from both sides )
2x = 10 ( divide both sides by 2 )
x = 5
substitute x = 5 into y = - 2x → y = - 10
solution is : (x, y ) → (5, - 10 )
(2)
equate the right sides of both equations
3x = 2x - 7 ( subtract 2x from both sides )
x = - 7
substitute x = - 7 into y = 3x → y = - 21
solution is : (x, y) → (- 7, - 21)
(3)
substitute y = - 8 into the other equation
- 8 = 6x + 22 ( subtract 22 from both sides )
- 30 = 6x ( divide both sides by 6 )
x = - 5
solution is : (x, y ) → (- 5, - 8 )

Answer:
Step-by-step explanation:
Variables : The value of a quantity which can be changed.
Monomial : Monomial contains only one term.
Example 3x, 4,6y² etc.
Binomial: Binomial contains two terms.
Example 3+4y, 20+7z etc
Trinomial: Trinomial contains 3 terms.
Example 5x-2y+5, 7z-3y+4x etc.
Given that,
[ It is a binomial.]
