How is table when constructing equations?

The numbers in a table are often the x and y values that are true for the line, which means the x and y values correspond to the coordinates of points on the line.

Given that a line equation is y=m x+b, the x and y values are numbers that can be used to arrive at the unknowns, such as the slope(m) and the y-intercept(b).

with the help of two points/coordinates we could find the slope of a line and the 3rd coordinate could be used to find the y-intercept.
