X intercept=5
Y intercept=-3
What you do:
To find the X intercept in an equation in standard form (Ax+By=C), you set the Y value to 0. Divide the A (3) into the C (15) and you get the x intercept.
To find the Y intercept, you do the opposite. Set the X value to 0 and divide the B (-5) into the C. You now have the Y intercept.
I hope this makes sense!

y - intercept occurs when x = 0 (since your graph cross the y-axis at x = 0) and your x - intercept occurs when y = 0.
3(0) - 5y = 15, so y = -3
y - intercept: (0,-3)
3x - 5(0) = 15, so x = 5
x - intercept: (5, 0)
3(0) - 5y = 15, so y = -3
y - intercept: (0,-3)
3x - 5(0) = 15, so x = 5
x - intercept: (5, 0)
