Answer:
A relationship between two variables in which one is a constant multiple of the other. In particular, when one variable changes the other changes in proportion to the first. If b is directly proportional to a, the equation is of the form b = ka (where k is a constant).
Step-by-step explanation: Find Y=Mx+B you find that so if it is Y-4x+3 B Is my slope so it would be *3* so go up 3 over to the negative 4 then do the same thing if you dont got any space then go up 4 over 3 and draw a line
