Tell whether the ordered pair is a solution of the system of equations.

(2.1)
2x+y=5
y = 4x– 1

1. No, (2,1) is a solution for y = 4x – 1 but not for 2x + y = 5.

2. Yes, (2,1) is a solution for both equations

3. No, (2,1) is a solution for 2x + y = 5 but not for y = 4x - 1

2x + y = 5

y = 4x – 1

Substitute (2, 1) into system, then:

2x + y = 5  => 2 x 2 + 1 = 5 => 5 = 5 (satisfied)

y = 4x– 1   => 4 x 2 - 1 = 1  => -7 = 1 (not satisfied)

=> Option 3 is correct.

Hope this helps!

step-by-step explanation:

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
