Question

Determine whether each ordered pair is a solution of the given linear equation.

2x + 7y = 16;
a. (9,1)
b. (8,0)
c. (0,0)

Answer 1

A. No

B. Yes

C. No

Step-by-step explanation: To determine if each pair is a solution to the equation, substitute the x and y variables in the pairs for the corresponding variables in the equation. If the left and right sides are equal once you solve, you will know that the pair is a solution,

(9,1) 2(9)+7(1)=16 18+7=16 25=16 No

(8,0) 2(8)+7(0)=16 16+0=16 16=16 Yes

(0,0) 2(0)+7(0)=16 0+0=16 0=16 No
