PLEASE HELP!

**Reiny**, Sunday, October 5, 2008 at 9:19pmslope is 7/7 = 1

so the equation is y = x+b

but (8,1) lies on it, so

1 = 8 + b

b = -7

your equation is y = x - 7

clearly the y-intercept is -7 by the definition of y = mx + b

for the x-intercept, let y=0 and solve for x

so just follow the rest of my solution with a slope of 7/2
