Why does it not matter what point you use on a line to determine the equation of it?
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.

How do you determine if a point lies on the same line?
A point lies on a line if the coordinates of the point satisfy the equation of the line.
Equation of a line and a point using substitution to determine whether the point is on the line y equals 5x plus 3 A18?
Yes its on the line.

How can you tell whether a point is on the line just by looking at its coordinates?
To determine if a point is on a line, you can use the equation of the line. For example, if the line is represented by the equation (y = mx + b) (slope-intercept form), substitute the x-coordinate of the point into the equation to see if the resulting y-value matches the point's y-coordinate. If they match, the point lies on the line; if not, it does not. Alternatively, you can use other forms of the line equation, such as standard form, to perform a similar check.
How do you find the equation of a line without graphing?
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,
How do you determine whether a point is on a given line or not?
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.
How do you determine if a point lies on the same line?
A point lies on a line if the coordinates of the point satisfy the equation of the line.
Equation of a line and a point using substitution to determine whether the point is on the line y equals 5x plus 3 A18?
Yes its on the line.
How do you determine if a certain point lies on a given line by just having the coordinates for the point and the equation of 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.
Determine the point at which the graph of the function has a horizontal tangent line for the equation?
For the equation (9x^2)/(x^2+4)
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 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
