Determine which ordered pair is a solution of y = –5x + 10. a. (–15, 5)b. (2, 0) c. (–1, –5) d. (3, 25)

Answers

y = - 5 x + 10
A ) x = - 15, y = 5
5 = 75 + 10
5 ≠ 85
B ) x = 2, y = 0
0 = - 5 · 2 + 10
0 = 0  ( correct )
C ) x = - 1,  y = - 5,
- 5 = 5 + 10
- 5 ≠ 15
D ) x = 3, y = 25
25 = - 15 + 10
25 ≠ - 5
Answer:
B ) ( 2, 0 )

Answer:

B. (2,0)

Step-by-step explanation:

The given equation is;

y=-5x=10

If an ordered pair is a solution, then the ordered pair must satisfy the given equation.

For (-15,5),we have

5=-5(-15)+10

5=75+10,this is FALSE.

For (2,0), we have

0=-5(2)+10

0=-10+10, this is TRUE

For (-1,-5), we have;

-5=-5(-1)+10

-5=5+10, this is FALSE.

For (3,25), we have;

25=-5(3)+10

25=-15+10, this is FALSE
