Use point-slope formula
+%28+y+-+0+%29+%2F+%28+x+-%28-4%29+%29+=+-3%2F5+
+y+%2F+%28+x+%2B+4+%29+=+-3%2F5+
Multiply both sides by +5%2A%28x+%2B+4%29+
+5y+=+-3%2A%28x+%2B+4%29+
+y+=+-%283%2F5%29%2Ax+-+12%2F5+
Here's a plot:
+graph%28+400%2C+400%2C+-10%2C+10%2C+-10%2C+10%2C+-%283%2F5%29%2Ax+-+12%2F5%29+
