given two points one a line (8,1) and 10,8) find the x intercept and y intercept
PLEASE HELP!

slope 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 yintercept is 7 by the definition of y = mx + b
for the xintercept, let y=0 and solve for x

when i did it i got the slope=7/2
how did you get 7/7?

you are absolutely right, my mental arithmetic is often pathetic.
so just follow the rest of my solution with a slope of 7/2

did you get yintercept of 27 and
xintercept of 54/7 ?
