Choose the correct graph that illustrates the equation by clicking on the image{(x, y): -1 ≤ x ≤ 3
ololo11 [35]

See attachment for the graph of the inequality -1 ≤ x ≤ 3

<h3>What is a linear inequality?</h3>

A linear inequality is an inequality that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

<h3>How to determine the correct graph?</h3>

In this question, the expression of the inequality is given as:

-1 ≤ x ≤ 3

The above means that the set of values of x is between -1 and 3 (-1 and 3 are inclusive of the values of x)

So, the possible values of x are -1, 0, 1, 2 and 3

When the graph of the inequality is plotted, the graph would have the following properties:

  • x values = -1, 0, 1, 2 and 3
  • Double closed circles or thick lines

Next, we plot the graph of the inequality -1 ≤ x ≤ 3

See attachment for the graph of the inequality -1 ≤ x ≤ 3
