Mini-Quiz: Linear Equations

1. Is 3×2 + 5 = 0 a linear equation?

   Yes, because it equals 0Good try, but not right. Select another answer. It depends on the value of xSorry, not correct. Try another button. No, because x2 is not a first order variableThat is correct. You know about linear equations.

2. Is y = ax + b a two variable linear equation if a = 0?

   Yes, because y = ax +b is the form of a two variable linear equationSorry, not correct. Try another button. No, because it becomes y = b, which is a one variable linear equationCorrect. You are doing great. It is both a one variable and two variable linear equationOops! Wrong answer. Re-read the question and try again.

3. Why do you make a table of values for x and y?

   It is a convenient way to list the values of y for different values of xThat is correct. You know about linear equations. It is an exercise to practice your arithmeticGood try, but not right.
