Let's start by understanding that the graph is a linear line. We have a common difference if 4.5 for every 10x we have more.

We can start by finding the gradient, using rise over run. Let's take (10, 4.5) and (20, 9)

Our rise is 9 - 4.5 = 4.5 and our run is 10. Then, our gradient becomes 4.5/10 = 0.45

Now, we can substitute points using the point-slope form.

y - 4.5 = 0.45(x - 10)
y - 4.5 = 0.45x - 4.5
Hence, our line becomes y = 0.45x and you can verify by substituting in points from the table.

Vikentia [17]

IL is a diameter, which is a straight line, which is equal to 180 degrees.

The arc of IL would be 180 degrees

You are told the arc of KL is 30 degrees.

The major arc of ILK would be 180 + 30 = 210 degrees.
