Is 2y = 5x - 8 standord form or slope intercept or neither?

I think it is slope intercept

This expression is slope intercept form.

Step-by-step explanation:

First, let's simplify, because I'm doing it for you, and it makes it less confusing :)

2y = 5x - 8

divide by 2 on both sides to isolate the Y

y = 2.5x - 4

that's definitely the slope intercept because it follows the Y = MX + B, which is slope intercept. My explanation may be a little confusing, so definitely comment on this answer if you need me to clarify. I hope this helps!
