Question 800669: find the slope-intercept when the x intercept is 3 and the y intercept is 3/5

The description means two points on the line are (3,0) and (0,3/5).

Apply the standard form equation for a line, .

The point (3,0) means

The point (0,3/5) means

The slope will be negative, considering those two axes intercepts. You should be able to algebraicly relate the standard form equation to the slope intercept form equation and see that , and you already have your "b", y-intercept.
'
Compute the value for the slope, m.

'
The equation for the line in slope-intercept form is then

You could convert that into standard form easily if you want.

Note, you can ignore "standard form" if you wish, and do everything according to definition of slope, and knowledge of slope-intercept equation form. The two given axes intercepts give you enough information.
