if we have an x-intercept of -2, we have one point at (-2,0)
and
a y-intercept of 1, , we have one point at (0,1)
we need a slope:
m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29 ...use points:
(-2,0) and (0,1)

m=%281-0%29%2F%280-%28-2%29%29
m=1%2F%280%2B2%29
m=1%2F2
use slope point formula:
y-y%5B1%5D=m%28x-x%5B1%5D%29.....plug in m=1%2F2 and coordinates of (-2,0)
y-0=+%281%2F2%29%28x-%28-2%29%29
y=+%281%2F2%29%28x%2B2%29
y=+%281%2F2%29x%2B1-> your line

-------------
If the x-int is (0,A) and the y-int is (0,B), the equation is
Bx + Ay = A*B
================
A = -2
B = 1
1x - 2y = -2*1
x - 2y = -2
