When discussing the key features of a linear graph, which of the following statements is true?

the points will make a straight line
the initial value is always zero
the points always have positive values
the rate of change can vary along the graph

1 answer

The true statement regarding the key features of a linear graph is:

the points will make a straight line.

In a linear graph, the relationship between the two variables is represented by a straight line, indicating a constant rate of change. The other statements are not necessarily true for all linear graphs:

  • The initial value is not always zero; it can be any value depending on the intercept.
  • The points do not always have positive values; they can be negative depending on the specific linear equation.
  • The rate of change in a linear graph is constant, not varying along the graph.
