f(g(x) = x, so it is the straight line through the origin, with a slope of 1.
A linear graph shows a linear equation in which the value of one variable depends on the value of the other variable.
A graph that shows proportions of different parts (of a whole) is a Pie chart.
A pie graph shows parts of a whole
A bar graph shows discreet data, but other types can also.
A line graph shows a trend over time.
If the graph shows a direct relationship, then the line will go up. If it shows an inverse relationship, the line will go down. A direct relationship means that as one variable increases, so does the other. On a graph, this means that as we move out along one axis, we also move out along the other. An inverse relationship means that as one variable increases, the other one decreases. So, for example, as we move to the right (X increasing), we have to move down (Y decreasing).
A graph of complimentary goods in economics represents the relationship between the price of of commodity & demand for it's complementary. Thus it shows a inverse relationship.
A bar graph.

A linear graph shows a linear equation in which the value of one variable depends on the value of the other variable.
Bar graph
The acceleration vs mass graph shows that there is an inverse relationship between acceleration and mass. This means that as mass increases, acceleration decreases, and vice versa.
Both show an amount of data, usually during a survey. One shows a number, but the other shows a percentage.
A graph that shows proportions of different parts (of a whole) is a Pie chart.
a pie graph shows percentages and a bar graph shows numbers and amounts
A pie graph shows parts of a whole
