The line goes through ( -3, 0 ) and ( 0, 2 )
The general form for a straight line is:
+y+=+m%2Ax+%2B+b+
-------------------
( -3,0 )
+0+=+m%2A%28-3%29+%2B+b+
+b+=+3m+
-------------------
( 0,2 )
+2+=+m%2A0+%2B+b+
+b+=+2+
--------------------
+b+=+3m+
+2+=+3m+
+m+=+2%2F3+
--------------------
The equation is:
+y+=+%282%2F3%29%2Ax+%2B+2+
--------------------
Here's the plot:
+graph%28+400%2C+400%2C+-5%2C+5%2C+-5%2C+5%2C+%282%2F3%29%2Ax+%2B+2+%29+
