The general form for a straight line is
+y+=+m%2Ax+%2B+b+ where
m = slope
+b+ = y-intercept
-------------------
given:
+m+=+6+
so far I have +y+=+6x+%2B+b+
and I am told
+y+=+f%28x%29+
+f%2812%29+=+13+
so,
+13+=+6x+%2B+b+
+13+=+6%2A12++%2B+b+
+13+=+72+%2B+b+
+b+=+-72+%2B+13+
+b+=+-59+
Now I have
+y+=+6x+-+59+ answer
