Question

determine if each statement about the graph is true or false.
statement\ttrue/false
the highest net electricity use occurred on july 4th.\ttrue/false
the net electricity use on july 2nd is represented by (2, -1).\ttrue/false

Explanation:

Step1: Analyze the first statement

The \(y -\)coordinate represents the net - electricity use. Looking at the points, the highest \(y -\)value (since \(y\) is the vertical axis representing the amount of electricity use) occurs at \(x = 4\) (July 4th). The \(y -\)value at \(x = 4\) is \(3\), which is higher than the \(y -\)values of other points (\(y=1\) at \(x = 1\), \(y = 0\) at \(x = 2\), \(y=2\) at \(x = 3\), \(y=-1\) at \(x = 5\), \(y = 0\) at \(x = 6\), \(y = 1\) at \(x = 7\)).

Step2: Analyze the second statement

For the point on July 2nd (\(x = 2\)), we look at its coordinates. The \(x -\)value is \(2\) and the \(y -\)value is \(0\) (since the point lies on the \(x -\)axis). The coordinate of the point is \((2,0)\), not \((2, - 1)\).

Answer:

The first statement is True. The second statement is False.
