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

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

We have:

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

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

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

$2\left(1\right)+2=4\phantom{\rule{0ex}{0ex}}2+2=4\phantom{\rule{0ex}{0ex}}4=4$

Both sides are equal.

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