How would you find the x and y intercepts for the equations x=3y, and x=7. For x=7 i know the x intercept is (7,0), but i'm not sure about the y. For the equation x=3y i'm not sure about either.

x=3y

the y intercept occurs when x=0

0=3y --means y = 0
point is (0,0)

the xitercept occurs when y=0
x= 3(0) -- means x=0
point is (0,0)



for x=7, there is no x intercept (ie at no point x=0)

For x=7 there is no y intercept, not no x intercept, the x intercept is (7,0). I think you made a mistake on that. Thank you for the rest!
