y=1.5x
The weight of one single Twix candy bar: 1.5 ounces.
1) A proportional relationship, graphically is described as a linear function with the line passing through the origin.
As we see in the graph.
2) If 20 candy bars weigh 30 ounces, then we can set a table:
Twix candy bar (x) | weight (y)
20 30
10 15
5 7.5
1 1.5
Therefore we can write an equation, for that proportional behavior:
y=kx
y=1.5x
The meaning of (1,1.5) is simply the unit rate for the Twix candy bar and its weight. Or in other words, the weight of one single Twix candy bar: 1.5 ounces.
3) The answers are:
y=1.5x
The weight of one single Twix candy bar: 1.5 ounces.
