Sorry, I want to clarify it now that someone is here to help.

The full question is:

An equation of the line that has a Slop of 3, and a y-intercept of -2 is....____

anonymous · Answer

Okay they've given you the slope and y intercept.
Just plug those back into the above equation.
$$y = mx + b$$
$$(output) = (slope)(input) + (intercept)$$
$$y = 3x - 2$$
