Question

graph.
x < 90
to draw a ray, plot an endpoint and select an arrow. select an endpoint to change it from closed to open. select the middle of the ray to delete it.

Explanation:

Step1: Analyze the inequality

The inequality \(x < 90\) means all real numbers less than \(90\).

Step2: Plot the endpoint

Since \(x\) is not equal to \(90\) (because of the strict inequality \( < \)), we use an open - circle at \(x = 90\).

Step3: Draw the ray

The values of \(x\) that satisfy \(x<90\) are to the left of \(90\) on the number line. So we draw a ray starting from the open - circle at \(90\) and extending to the left.

Answer:

Plot an open - circle at \(90\) on the number line and draw a ray extending to the left from that open - circle.
