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 given by the equation y-7x?
y - 7x is not an equation but an expression. It cannot, therefore, define a line.
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?
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.
