Question8 Which of the following equations represents a line without a $y$-intercept? (a) $y=4$ (b) $x=-4$ (c) $x+y=2$ (d) $y=3 x$

Studdy Solution
Determine which equation represents a vertical line.
From STEP_1, we identified that equation (b) $x = -4$ is a vertical line.
The equation that represents a line without a $y$-intercept is:
$\boxed{x = -4}$
