Use the slope and coordinates to solve for b, y-intercept.
5= -3(0) + b
b = 5

Use the formula:
+%28+y+-+5+%29+%2F+%28+x+-+0+%29+=+%28+-7+-+5+%29+%2F+%28+4+-+0+%29+
+%28+y+-+5+%29+%2F+x+=+%28+-12+%29+%2F+4+
+%28+y+-+5+%29+%2F+x+=+-3+
+y+-+5+=+-3x+
+y+=+-3x+%2B+5+
------------------
check:
(4,-7)
+y+=+-3x+%2B+5+
+-7+=+-3%2A4+%2B+5+
+-7+=+-12+%2B+5+
+-7+=+-7+
(0,5)
+5+=+-3%2A0+%2B+5+
+5+=+5+
OK
