Which of the following is true to xy = 8?
xy = 8 is not a linear equation in two variables because x and y are one term.
xy = 8 is linear equation in two variables because it has variables x and y.
xy = 8 is linear equation in two variables because x and y are one term.
None of these.
Is the equation x2 – y = 9 a linear equation in two variables? Why?
No, because the exponent of x is in degree 2.
Yes, because the exponent of x is in degree 2.
No, because x2 – y = 9 is just the same with Ax + By = C.
Yes, because x2 – y = 9 is just the same with Ax + By = C.
Is the equation x6 + 7y = 9 a linear equation in two variables?
No, because the variable x appears in the denominator of a fraction.
Yes, because the variable x appears in the denominator of a fraction.
No, because x6 + 7y = 9 is just the same with Ax + By = C.
