If a direct relationship exists between variable a and variable b, what would happen to variable b if variable a is increased? it will increase too. it will decrease. it will go up and down in a cycle. it will respond randomly.

If Variable A is increased, Variable B will increase too. In a direct relationship, the two variables move in the same direction - if one increases, the other does too, and vice versa. In an inverse relationship, the two variables move in opposite directions - if one increases, the other decreases.
