Hi
For Example:
Line: y = x + 4, crosses the y-axis at Pt(0,4) That is: x = 0
Line: y = x + 4, crosses the x-axis at Pt(-4,0) That is: y = 0
If the point is on the y axis(y-intercept)...x will be zero
If the point is on the x axis(x-intercept)...y will be zero
Picturing the graphing has always been helpful to me.
Hope it works for You!
