b) Yes. Because it grows linearly, and have the proportions of 3. For each x you have an y 3 times bigger
Step-by-step explanation:
a) Okay, I cannot draw it right now, but I can explain how you'll do it. First step: draw a point on x=1 and y=3. Second step: draw another point on x=5 and y=15. Third step: pick your rule and make a straight line in these two points. It's done :)
The equation would be d - 19 = 73. So the zoologist would take the number of deer recorded and subtract it from 19 (since it said 19 fewer deer) and the answer would be 73 (because that is how many deer were recorded a year later. I hope this helps!
