Question

1. The point (3, 1) is on the line whose equation is 2x + y = c. What is the value of c?

Answer 1

Answer:

c = 7

Step-by-step explanation:

Given

2x + y = c

Since (3, 1) is on the line then it makes the equation true,

Substitute x = 3, y = 1 into the equation

2(3) + 1 = c

6 + 1 = c

7 = c
