**Reiny**, Thursday, April 23, 2009 at 3:41pmthen let x = 0

so y = 3(0) + 18(0) = 0

the y-intercept is 0, the line runs through the origin.

**kirs**, Friday, April 24, 2009 at 5:55pmsorry i meant the x intercept

**RickP**, Friday, May 1, 2009 at 1:16amx intercept:

y = 3x^2+18x

0 = 3x^2+18x

3x is common to both terms on the right: factor it out.

0 = 3x(x + 6)

If 2 values are multiplied together and the product is 0, then one or both of the values must be 0.

3x = 0 and/or x + 6 = 0

Take it from there.
