Question

what is the scale of the graph (y-axis)? example of a line graph push - ups number of push - ups 0 5 10 15 20 25 30 days sunday monday tuesday wednesday thursday friday saturday push - ups (with options: 1, days of the week, 5 shown with radio buttons)

Explanation:

Step1: Identify y - axis intervals

The y - axis (number of push - ups) has markings at 0, 5, 10, 15, 20, 25, 30. To find the scale, we calculate the difference between consecutive markings. Let's take two consecutive values, say 0 and 5. The difference is $5 - 0=5$. We can check with other consecutive values: $10 - 5 = 5$, $15 - 10=5$, and so on.

Step2: Determine the scale

Since the difference between each consecutive marking on the y - axis is 5, the scale of the graph (y - axis) is 5.

Answer:

5
