Algebra practice question

In the xy-plane, the line 2x − 4y = 8 has slope m. What is the value of 1/m?

Answer: 2

−4y = −2x + 8 gives y = x/2 − 2, so m = 1/2 and 1/m = 2.

Common wrong answers

If you answered 4
4 uses m = 1/4.
If you answered 0.5
0.5 is m itself.
If you answered -2
−2 has the sign wrong.
