**Reiny**, Monday, September 5, 2011 at 12:49pmfor x-intercept , let y = 0

x^2 + 0 + 0 - 2x + 0 = 8

x^2 - 2x - 8 = 0

(x-4)(x+2) = 0

x = 4 or x = -2

so the x-intercepts are (4,0), and (-2,0)

for the y-intercepts, let x = 0

0+y^2 + 0 - 0 + 7y =8

..

..

you finish it, let me know what you get.
