Chapter 1: Q. 6 (page 40)

True or false The point $(1, 2)$ is on the line $2 x + y = 4$ .

Short Answer

Expert verified

The statement "The point $(1, 2)$ is on the line $2 x + y = 4$ ." is true.

Step by step solution

01

Step 1. Given information.

We have:

$2 x + y = 4$ and the point $(1, 2)$ .

02

Step 2. Find whether the statement is true or false.

The equation is $2 x + y = 4$ and the point is $(1, 2)$ .

Substitute the value of $(x, y) = (1, 2)$ into the equation.

$2 (1) + 2 = 4 2 + 2 = 4 4 = 4$

Both sides are equal.

Hence, $(1, 2)$ is the point lie on the line $2 x + y = 4$ .
