Classify stars and to understand how stars change over time
Newtown and Kepler were two famous astronomers during the Renaissance.
Yes, an HR diagram plots a star's luminosity (brightness) against its surface temperature, also known as color or spectral type. This graph shows the relationship between these two characteristics for different stars, allowing astronomers to classify and study them.
Parallax is the apparent change in postion of an object when looked at from two different places. Astronomers use parallax to find how far away nearby stars are.
Two famous astronomers during the Renaissance were Nicolaus Copernicus, who proposed the heliocentric model of the universe, and Galileo Galilei, who made significant observations with his telescope supporting the heliocentric model and challenging the geocentric view of the universe.
Nicolaus Copernicus and Johannes Kepler were two famous astronomers during the Renaissance period. Copernicus is known for proposing the heliocentric model of the universe, while Kepler is known for his three laws of planetary motion.
Two ways to be able to identify a physical property are the color and the concistancy.
The two ways is through sounds that are aspirated and not.
microlensing
This plot is commonly referred to as a Hertzsprung-Russell (H-R) diagram, named after the astronomers Ejnar Hertzsprung and Henry Norris Russell who independently developed it in the early 20th century.
The two characteristics of a star plotted on the Hertzsprung-Russell diagram are luminosity (brightness) on the y-axis and temperature or spectral type on the x-axis. This diagram helps astronomers classify stars according to their different stages of evolution.

It means that the two measurements that are plotted on the H-R diagram - its luminosity and its spectral type (equivalent to its temperature) - change.
See the related links for two ways to do it.
the color and streak or luster
Two ways to determine whether the relation is a function is use a mapping diagram or use a vertical line test.
A diagram that shows how two variables are related is called a "scatter plot." It is a visual representation of the relationship between the two variables, often used to identify patterns or trends in the data.
