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.
What does solving the equation for a line tell us?
A line is represented by an equation. Each solution of the equation is a point on the line, and each point on the line is a solution to the equation. So the line is just the graph of the solution set of the equation.
How do you calculate the equation of a line that is undefined?
The equation is the definition of the line.If the line is undefined, then it has no equation.
What is a equation of a line?
The equation of any horizontal line isY = a number
What is the equation of a line with a slope of zero?
A horizontal line has a slope of zero. The equation of a horizontal line is y = a.
When does an equation graph a line?
When it is a linear equation.
What is the name of an equation of a line?
It is a linear equation.
What is the equation of a line?
The equation of a line is y=mx+b, when m is the slope of the line and b is the y-intercept.
An equation where the graph of all solutions lies on a line?
If it is a straight line, then the equation is linear.
Which equation represent a line parallel to the line whose equation is 2y 5y equals 10?
When a straight line equation is parallel to another equation the slope remains the same but the y intercept changes
Given the equation of a line how is the slope calculated?
If the equation of a line is in the form ax + by + c = 0 then the slope of the line will be -a/b.
When an equation forms a straight line what is it?
a linear equation.
What is the general form for a line equation?
General form for a line equation is: y=mx+b.
