The answer is 2
bar graph
The slope of a graph.
graph
A line graph.
speed is the gradient under the distance vs time graph which is change in distance /change in time
When thermal energy is added to a substance, its atomic or molecular activity will increase, leading to higher kinetic energy and greater movement of particles. This can cause the substance to change state, such as melting from a solid to a liquid. The shape of the graph representing temperature changes may show plateaus where phase transitions occur before the temperature starts to rise again.

The phase change of water graph shows the relationship between temperature and state of water. It includes the three main phases of water: solid (ice), liquid (water), and gas (steam). The graph illustrates how water transitions between these phases with changes in temperature and pressure.
Rate of change is essentially the same as the slope of a graph, that is change in y divided by change in x. If the graph is a straight-line, the slope can be easily calculated with the formula:Vertical change ÷ horizontal change = (y2 - y1) / (x2 - x1)
o function is given. However, if linear , then the rate of change is the same as the steepness of the graph line.

A line graph.

A line graph is useful for showing trends or continuous change. Other kinds of graph also will show these, but a line graph is usually clearest.
