What is the equation of the line with an x-intercept of -1 and a y-intercept of 2?
-------
The long way, using the 2 points (-1,0) and (0,2)
Slope m = diffy/diffx = 2/1 = 2
----------
Use y-y1 = m*(x-x1) where (x1,y1) is either point.
y-2 = 2*(x-0) = 2x
y = 2x+2 is an equation, not "the" equation.

The slope is m
The intercept is b, and this is a point on x where y = 0
The slope-intercept is y = mx + b
.
m(-1) + 2 = 0
m(-1) = -2
m = -2/-1
.
now that we know m, we can complete the equation:
y = -2/-1x + 2
.
