1. The x-intercept of a line is -3. The y-intercept of a line is 6. What is the slope of the line?

2. What is the equation in slope-intercept 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 x-intercept of -3 is really the point (-3,0)
and a y-intercept of 6 is the point (0,6)

so slope of line = (6-0)/(0-(-3)) = 2

2.
so in y = mx + b, m is the slope and b is the y-intercept, so just put the stuff in there

y = 2x + 6
