Step-by-step explanation:
(a)
For the graph to display direct proportion it must pass through the origin.
The graph shown does not pass through the origin thus does not represent direct proportion.
(b)
Given that q is directly proportional to r then the equation relating them is
q = kr ← k is the constant of proportion
To find k use the condition q = 76 when r = 20, thus
76 = 20k ( divide both sides by 20 )
3.8 = k
q = 3.8r ← equation of proportion
When r = 45, then
q = 3.8 × 45 = 171

<span>Each paper clip can be traded for three matches.
Each pencil can be traded for six paper clips which can be traded for (6 x 3 = 18) eighteen matches.
</span><span>Two pencils and two paper clips are worth (2 x 18 + 2 x 3 = 36 + 6 = 42) which is greater than thirty-eight matches.
Therefore, </span><span>Two pencils and two paper clips are worth thirty-eight matches.</span>
Hey there! :D
Let's break this up piece by piece.
The first two, let's say that the first boxes represent the bottom of the chart.
The first far left box would be 13.
The next one 9.
Going across, 10 and 11.
Two more up.
7 and 3.
One more across, which is 4.
So, 13, 9, 10, 11, 7, 3, 4 would be the ones you would want to shade.
I hope this helps!
