(y -y1)=(x -x1)(y2 -y1)/(x2 -x1) defines the line containing coordinates (x1,y1) and (x2.y2).

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.
An equation for a line in the plane allows you to find the x- and y-coordinates of any point on that line?
True.
What points are on the line given by the equation y equals x?
Y Equals X PointsAll points that has the same y coordinates as x coordinates are on the y=x line.
How do I write the equation of the line that passes through the given point and is perpendicular to the given line Write the answer in slope-intercept form?
The standard equation for a straight line is y = mx + c. Let this be the equation of the original line. Note that m and c are known values. Let the given point coordinates be (a,b)Two straight lines are perpendicular if the product of their gradients (slopes) is -1.The slope (m1) of the perpendicular line is therefore m1 = -1/mWhen y = b then x = a so the equation for the perpendicular line is y = m1x + d, and substituting gives : b = -a/m + d and this will enable d to be calculated.NOTE : In the absence of information for the equation of the original line and the coordinates of the given point then this is a general rather than a specific answer.
Find slope of the line ab?
If point a has coordinates (x1,y1), and point b has coordinates (x2, y2), then the slope of the line is given by the formula: m = (y2-y1)/(x2-x1).
How can you find the coordinates of two lines mathematically given the equation of both?
Subtract the equation of one line from the equation of the other
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 find coordinates of a line from an equation without graphing?
By substitution
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.
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
How can you check if a point is on a given line?
Improved Answer:Find the equation of the line that is given.Check to see if the coordinates of the point satisfy the equation of the line.-411LeonOld Answer:Don't ask us!!
What does the equation allows you to find on any point on the line?
The x and y coordinates
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.
How do you find a point lying on the line?
Substitute the coordinates of the point into the equation of the line. If the result is true, then the point is on the line.
An equation for a line in the plane allows you to find the x- and y-coordinates of any point on that line?
True.
What points are on the line given by the equation y equals x?
Y Equals X PointsAll points that has the same y coordinates as x coordinates are on the y=x line.
An equation allows you to find the x- and coordinates of any point on the xy - plane?
Yes if it is a straight line equation
