x intercept: (6,0)
y intercept: (0,16)

Explanation:

The x intercept is a point on the x axis, so it's a point with coordinates (x,0). Similarly, a point on the y axis is a point of the form (0,y).

So, you find the intercept with one axis by setting the other variable to 0:

y-intercept: set the x coordinate to zero.

8*0+3y=48

3y=48

y=16

So, the point (0,16) belongs to the line, and it is its y incercept.

x-intercept: set the y coordinate to zero.

8x+3*0=48

8x=48

x=6

So, the point (6,0) belongs to the line, and it is its x incercept.
