How can you find equation of the line passing thruogh two points?
. the equation of a straight line can be found by using two points on a line . First find the gradient of the line using the gradient formula . now substitute the gradient into general form replacing "m" . use one of the points and substitute into equation to solve "c" example 1: find the equation of the line which passes through the points (1,3) and (2,5). step 1: find the gradient M=5-3/2-1=2 (/=divide) step 2: place m into the equation Y=2x+c step 3: substitute point into equation 3=2(1)+c step 4: solve C=1 equation is Y=2x+1 hope that helps :)
How can you find an equation line between two pair of points?
Assuming you want the equation of the straight line between the two points (x0, y0) and (x1, y1), the equation is: y - y0 = m(x - x0) where m is the gradient between the two points: m = (y1 - y0) ÷ (x1 - x0) Note: if the two x coordinates are equal, that is x0 = x1, then the equation of the line is x = x0.
How do you work out gradients and intercepts?
Gradients can be worked out by: 1. gradient formula, suppose the two points are (x1,y1); (x2,y2) then the gradient=(y2-y1)/(x2-x1) 2. rise/run Intercepts can be found by: 1. to find the x-intercept substitute y=0 into the equation of the line 2. to find the y-intercept substitute x=0 into the equation of the line
One way to find the equation of a line is to look at some points on it and try to find the relationship between the coordinates?
Yes. You need only two points. If A (ax, ay) and B (bx, by) are two points on the line then the gradient (slope) of the line is m = (by - ay)/(bx - ax) provided bx ≠ ax. From this you can calculate m. Then the general slope-intercept form of the equation is y = mx + c Substitute the coordinates of A or B into this equation to find c. If bx = ax then the line is parallel to the y axis and its equation is x = ax. [There are other methods but they are similar to the above]
How can you find the unit rate from a line on a graph that goes through the origin?
It is the gradient of the line. Pick any two points on the line. Measure the RISE = difference in their heights (distances from the x-axis), and the RUN = difference in their horizontal displacements (distances from the y-axis). The unit rate is RISE/RUN.
How do you find the gradient of a line from a graph?
Select two points on the graph and suppose their coordinates are (x1, y1) and (x2, y2) then the gradient = (y1 - y2) / (x1 - x2) provided that x1 and x2 are different. If not, the gradient is not defined.
Can any 2 points on a straight line be used to find the gradient?
Yes beccause: (y1-y2)/(x1-x2) = gradient
How do you show that two points are parallel to two other points?
Points cannot be parallel to other points. A straight line joining two points is parallel to a straight line joining another pair of points if the gradient (slope) of the two lines is the same.

What two variables do you need to know to determine the gradient between two points on a map?
The height of the land, and the scale of the map
When you have three collinear points there is exactly one?
When you have three collinear points there is one gradient. I'm not sure what your question is specifically but when points are collinear they have the same gradient.
How do you find the temperature gradient between two thermometers?
To find the temperature gradient between two thermometers, subtract the temperature reading of the first thermometer from the temperature reading of the second thermometer. This difference represents the temperature change over the distance between the two thermometers, indicating the temperature gradient.
What is the does this definition go with- The slope of a line conecting two points?
The gradient is a measure of steepness from one point to another.
What is the gradient of a triangle?
find the gradient
How can you find an equation line between two pair of points?
Assuming you want the equation of the straight line between the two points (x0, y0) and (x1, y1), the equation is: y - y0 = m(x - x0) where m is the gradient between the two points: m = (y1 - y0) ÷ (x1 - x0) Note: if the two x coordinates are equal, that is x0 = x1, then the equation of the line is x = x0.
How do you use rise and run math?
Provided the run is not zero, rise/run gives the gradient, or slope, between two points.
Two points 10 meters horizontally apart have a difference in elevation of 1.5 mtrs what is the gradient of these two points in percentage and degrees?
The slope of the line between the two points is (1.5/10) = 15% .The angle is the angle whose tangent is 0.15, roughly 8.53 degrees (rounded)
