Ответ:
B
Step-by-step explanation:
Given
5 - 2x + 7y = 4 ( subtract 5 from both sides )
- 2x + 7y = - 1 ( add 2x to both sides )
7y = 2x - 1 ( divide all terms by 7 )
y =
x - 
→ B
Ответ:
B.
Step-by-step explanation:
We have been given an equation
. We are asked to choose the equation that is equivalent to our given equation.
We will convert our given equation in point-slope form of equation.
Divide both sides by 7:
Therefore, equation
is equivalent to our given equation and option B is the correct choice.
Ответ:
C.
Step-by-step explanation:
The set of ordered pairs can only be a function if the x value is not repeated .Thus,only C is a function as the x values (-1,4,1,-3) are unique while the other options have a repetition of its certain x values.
