Question

How do you determine whether the y-value of the y-intercept is negative, positive or zero?

Answer 1

by plugging in x=0 and checking the results ...

Answer 2

ax + by = c

yint = c/b is a simple check as well

Answer 3

what if you get a graph and have to determine it. If the slope is positive, is the y-int positive too?

Answer 4

if you get a graph; you just see where the graph crosses the y axis at

Answer 5

slope doesnt determine yint; x=0 does

Answer 6

okay. thanks again.

Answer 7

yep
