You can put this solution on YOUR website!
The x-intercept ocurrs where +y+=+0+
The y-intercept ocurrs where +x+=+0+
So, you are looking for 2 points:
x-intercept: (x,0)
y-intercept: (0,y)
----------------
(x,0)
+-2x+%2B+y+=+4+
+-2x+%2B+0+=+4+
+-2x+=+4+
+x+=+-2+
------------
(0,y)
+-2%2A0+%2B+y+=+4+
+y+=+4+
----------
Here' the plot. It shows the intercepts at
(-2,0) and {0,4)

Find x-intercept(s) by setting y=0:
y=0
-2x +(0)= 4
-2x=4
x=-2
x-intercept (-2, 0)
Find y-intercept by setting x=0:
x=0
-2(0)+y=4
y=4
y-intercept (0, 4)
