Answer:
3(7+5)
Step-by-step explanation:
21+15
Each term is divisible by 3
3*7 +3*5
3(7+5)
You can't. If you think about the straight line on a graph, those numbers
describe a single point that the line goes through, and they don't tell you
anything about the slope of the line, or where it crosses the x-axis or the
y-axis. So I don't think you can tell the constant of variation from one point.
= 81
