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.
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
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+2y=12?

Yes, I'm confident of that.
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.
The equation is the definition of the line.If the line is undefined, then it has no equation.
The equation of any horizontal line isY = a number
A horizontal line has a slope of zero. The equation of a horizontal line is y = a.
When it is a linear equation.
It is a linear equation.
The equation of a line is y=mx+b, when m is the slope of the line and b is the y-intercept.
If it is a straight line, then the equation is linear.
When a straight line equation is parallel to another equation the slope remains the same but the y intercept changes
If the equation of a line is in the form ax + by + c = 0 then the slope of the line will be -a/b.
General form for a line equation is: y=mx+b.
