Question

Select all the ordered pairs that are solutions of the equation.

A. (-7, 1)
B. (-1,7)
C. (0,5)
D. (2,3)
E. (3, 2)
F. (5,0)

Answer 1

B. (-1,7)

C. (0,5)

D. (2,3)

Explanation:

We solve this question looking at the graphic.

A. (-7, 1)

When
`x = -7, y \rightarrow \infty`, and thus (7,-1) is not solution of the equation.

B. (-1,7)

When
`x = -1, y = 7`, and thus (-1,7) is a solution of the equation.

C. (0,5)

When
`x = 0, y = 5`, and thus (0,5) is a solution of the equation.

D. (2,3)

When
`x = 2, y = 3`, and thus (2,3) is a solution of the equation.

E. (3, 2)

When
`x = 3, y \\eq 2`, and thus (3,2) is not part of the solution

F. (5,0)

When
`x = 5, y \\eq 0`, and thus (5,0) is not part of the solution
