Answer:
1. variable = x
2. constant = 1, variable = a
3. variables = x and y
4. variables = r and s
5. constant = -11, variables = a and b
Step-by-step explanation:
- Constant: a number on its own
- Variable: a symbol for a unknown value. It is usually a letter such as x or y
- Coefficient: a number used to multiply a variable
1. variable = x
2. constant = 1, variable = a
3. variables = x and y
4. variables = r and s
5. constant = -11, variables = a and b
