Answer:
the answer would be m=1/3 and b=-4
Step-by-step explanation:
Y=X-4
the X= 1 almost all the time in an equation unless otherwise your given an equation for "x". so x is automatically 1/3 which would be your slope, and then then looking at the equation the end part of the equation is your starting point.so you look at the end of the equation and the -4 is were youd start your point on the graph.
