1. The xintercept of a line is 3. The yintercept of a line is 6. What is the slope of the line?
2. What is the equation in slopeintercept form of the line described in Exercise 1?
can you please explain and answer it?? im having lots of trouble with this.
it's urgent... thanks a lot.. :)

1.
remember, an xintercept of 3 is really the point (3,0)
and a yintercept of 6 is the point (0,6)
so slope of line = (60)/(0(3)) = 2
2.
so in y = mx + b, m is the slope and b is the yintercept, so just put the stuff in there
y = 2x + 6
