adelina 88 [10]

X intercept is where the line crosses the x axis or where y=0
y intercept is where the line crosses the y axis or where x=0

so

6x-3y=-6
x intercept
y=0
6x-3(0)=-6
6x=-6
x=-1
x intercept at x=-1 or the point (-1,0)

y intercept
x=0
6(0)-3y=-6
-3y=-6
y=2
y intercept at y=2 or the point (0,2)
