The equation of a line in slope-intercept form (y = m*x + b) involves constants m and b, the independent variable x and the dependent variable y. The constants m and b are properties of the whole line and do not depend on the point chosen.
There are actually infinitely many equations that represent a given line. In fact, there is another form of a line equation called two-point form [y - y1 = (y2 - y1)/(x2 - x1)(x - x1)]. Obviously a different equation can be determined for any pair of points ((x1, y1), (x2, y2)) on the line.
A point lies on a line if the coordinates of the point satisfy the equation of the line.
Yes its on the line.
For the equation (9x^2)/(x^2+4)
There are a couple ways to determine the equation of a line without graphing. How to proceed depends on what you know about the line. Do you know a point, (x1, y1), and slope, m? Then use the point-slope formula, Do you know two points on the line, say (x1, y1) and (x2, y2)? Then use the two-point formula,
Substitute the coordinates of the point into the equation of the line. If the result is true, then the point is on the line.
Substitute the coordinates of the point into the equation of the line. If the equation is still valid then the point is on the line; if not then it is not.
A point lies on a line if the coordinates of the point satisfy the equation of the line.
Yes its on the line.
Substitute the x coordinate into the equation for x and calculate y. If the formla gives the same y value as the coordinates, the point is on the line. If it is diffent, it is not on the line.
For the equation (9x^2)/(x^2+4)
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.
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

If a point on a line is already known, what else is needed in order to create an equation
You can have infinitely many lines through one specific point, each with a different equation. If you want to have a general equation for ANY line that goes through that point, use the point-slope equation for a line, and use a variable for the slope.
