Question

Consider the following equation.

x+4y=14
Determine the missing coordinate in the ordered pair (−2,?) so that it will satisfy the given equation.

Answer 1

Answer:  4

Explanation:

We plug in x = -2 and solve for y

x+4y = 14

-2+4y = 14

4y = 14+2

4y = 16

y = 16/4

y = 4

Therefore, the point (-2, 4) is on the line x+4y = 14.
