There are several equations; sometimes one can be more appropriate, sometimes another, depending on what data is given. For example, an equation solved for "y", i.e. of the form
y = mx + b
directly shows you the line's slope (which is "m") and the y-intercept (which is "b"). On the other hand, a general form of an equation of a line is
ax + by = c
This form is able to represent vertical lines, which can't be expressed with the slope-intercept form. There are several other equations for a line as well.

How do write an equation of a line when given the slope a point of the line?
if a line has a slope of -2 and a point on the line has coordinates of (3, -5) write an equation for the line in point slope form
What is the slope of the line that has the equation 4x plus 2y equals 12?
what is the slope of the line that has the equation 4x+2y=12?
What is the slope of the line given by the equation y-7x?
y - 7x is not an equation but an expression. It cannot, therefore, define a line.
Which equation represents a line that is parallel to the line y equals 3-2x?

If you are given the graph of a line in an xy-plane and its corresponding equation you can be sure that the coordinates of every point on that line will satisfy the equation?
Yes, I'm confident of that.
