Video Solution

Solution Steps

00:00 Find the price for 7 kg of apples
00:03 The X-axis represents the weight of apples, we find 7
00:07 Draw a perpendicular line to the Y-axis which represents the price
00:15 And this is the solution to the question

Step-by-Step Solution

Let's first observe the X-axis which is representative of the weight. Locate 7 kg - and mark a point.

From this point, we'll draw a vertical line until we meet the straight line.

Let's now observe the Y-axis which is representative of the price.

We will draw a line from the point where we reached the X-axis to the straight line, towards the Y-axis and determine the price: 8 dollars.
