Consider that x = −9 and y = −6. Which statement is true about x + y?
2 answers:
Answer: A) The sum of x and y is a rational number.
Step-by-step explanation:
A rational number is a number that can be expressed as a fraction , that is , it can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number
since x = -9 and y = -6
x + y = -9 + -6
x + y = -15
-15 can be written as -15/1 , this shows that it is a rational number.
Note : Irrational numbers can not be expressed as fraction ,example is ,
and so on
Also , Imaginary number is a complex number

x + 6y = 12
You want the y-value to be on one side of the equation, so you have to subtract the x-value from both sides.
6y = -x + 12
Next, you divide both sides by 6, so that the y-value will be by itself.
y = - + 2
We know that the slope or the 'm' value is located before the x-value based on y = mx +b, therefore the slope is -
