Use the point-slope formula
+3%2F2+=+%28y+-+4%29+%2F+%28x+-+7%29+
Multiply both sides by +2%2A%28x+-+7%29+
+3%2A%28x+-+7%29+=+2%2A%28y+-+4%29+
+3x+-+21+=+2y+-+8+
+2y+=+3x+-+21+%2B+8+
+2y+=+3x+-+13+
+y+=+%283%2F2%29%2Ax+-+13%2F2+
Check answer:
Does line go through (7,4) ?
+4+=+%283%2F2%29%2A7+-+13%2F2+
+8+=+21+-+13+
+8+=+8+
OK
