Question

Which statements are true the ordered pair (1, 2) and the system of equations?

y = -2x + 4
y = 7/2x - 3/2

Answer 1

Statements:

- When (1, 2) is substituted into the second equation, the equation is true

- The ordered pain (1, 2) is a solution to the system of linear equations

- When (1, 2) is substituted into the first equation, the equation is true.

Explanation:

Statement 1:

y= 7/2x - 3/2

2= 7/2 * 1 - 3/2

2= 7/2 -3/2

2=4/2

2=2

Statement 2:

y= -2x + 4

2= -2 ( 1 ) + 4

2= -2 + 4

2 = 2

Statement 6:

y= 7/2x - 3/2

2= 7/2 * 1 - 3/2

2= 7/2 -3/2

2=4/2

2=2

y= -2x + 4

2= -2 ( 1 ) + 4

2= -2 + 4

2 = 2
