Points: (1, 6) and (5, 9)
Slope or gradient: (9 -6)/(5 -1) = 3/4
Equation: y -6 = 3/4(x -1)
y = 3/4x -3/4+6 => y = 3/4x+21/4
Which can be expressed in the form of: 3x -4y+21 = 0

What are points on a line for geometry?
In coordinated geometry the points on a straight line will determine its equation.
Why do you need to find the equation of a line?
So that you can plot out the points of a straight line on graph paper.
What is the equation of the line containing the points (3 1) (9 3) (27 9)?
The straight line equation works out as: 3y = x
Do four points lie on the same plane?
Yes, when they are the coordinates of a straight line equation.
What defines a line as straight on a graph?
Two points. An intercept and an angle. Answer: When the equation of the line has x as a simple multiple of y, the line is straight (e.g x=m+by)

What is a straight line that joins two points on the circumference of a circle?
A chord is a line that joins to points on the circumference of a circle. If it passes through the center of the circle it's called a diameter.
Why do you need to find the equation of a line?
So that you can plot out the points of a straight line on graph paper.
A set of points arrange in a row?
They could be the coordinates of a straight line equation
A straight path that extends infinitely in opposite directions?
A line is a straight path that extends infinitely or endlessly in opposite directions. A straight path that joins two points is called a line segment.
What is the equation of the line that passes through the points (-42) and (4-2)?
If you mean points of (-4, 2) and (4, -2) Then the straight line equation works out as 2y = -x
What is the equation of the line containing the points (3 1) (9 3) and (27 9)?
The straight line equation works out as: 3y = x
What is the equation of the line containing the points (3 1) (9 3) (27 9)?
The straight line equation works out as: 3y = x
Why is it true that any two points satisfying a linear equation will give you the same graph for the line representedby the euqation?
-- The graph of a linear equation is a straight line. -- Any two points on a straight line are enough to completely specify the line, that is, to uniquely identify the line and tell you everything there is to know about it.
What is are the determinants of fertilty?
alternatives to determine the equation straight line through two points?
Java code equation of a straight line given two points?
