# How do you write the equation of a line in point slope form that is parallel to y=5x+4 and goes through (0,0)?

To be parallel it must have the same slope which is $m = 5$ (the coefficient of $x$ in your equation). You can use the relationship:
$y - {y}_{0} = m \left(x - {x}_{0}\right)$
$y - 0 = 5 \left(x - 0\right)$ in Point-Slope form.
