$y$y is equal to $7$7 less than $2$2 groups of $x$x

Write the statement above as a mathematical equation.

Is this equation linear?

Yes

No

$y$y equals $x$x divided by $2$2 plus $8$8.

$y$y plus the quotient of $x$x and the square of $-4$−4 is equal to $14$14.

$y$y equals $-1$−1 divided by $x$x plus $6$6.

Determine, through investigation, the characteristics that distinguish the equation of a straight line from the equations of nonlinear relations
