The slope-intercept form of a linear equation is:
+f%28x%29+=+m%2Ax+%2B+b+
+m+ is the slope of the line
+b+ is the y-intercept
-----------------
+f%28-7%29+=+0+
+m+=+-1%2F4+
----------------
+f%28x%29+=+%28-1%2F4%29%2Ax+%2B+b+
+f%28-7%29+=+%28-1%2F4%29%2A%28-7%29+%2B+b+
+f%28-7%29+=+7%2F4+%2B+b+
+7%2F4+%2B+b+=+0+
+b+=+-7%2F4+
----------------
The equation is:
+f%28x%29+=+%28-1%2F4%29%2Ax+-+7%2F4+
