  1. Which graphs represent linear relations? Explain.














    Which graphs represent linear relations? Explain.














    1. Graph a is a non-linear relation because if the points were to be connected, a straight line would not be formed. The graph is not a relation since a trend is not evident.

    2. Graph b is a linear relation because the line drawn is straight, and a general trend can be seen.

    3. Graph c is a non-linear relation because the line drawn is not straight, but a general trend can be seen.

    4. Graph d is a linear relation because the line drawn is straight, and a general trend can be seen.
