Rearranging: 3y=8x+15 or y=8x/3+5. This is now in standard form, so the y intercept is 5. Rather than find the x intercept, we can look for an easy value of x that gives us a convenient value for y. Put x=3 to cancel the 3 in the denominator, then y=13. So mark the points (0,5) and (3,13) and draw a line through the two points. This is the graph representing the equation.
