Question

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)?

Answer 1

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(x-x_0)`
`y-0=5(x-0)` in Point-Slope form.
