Say your two points are (-1,-2) and (3,4). Your y intercept is where the line your two points make crosses the y axis. You find this by taking one of your coordinates, (3,4) and you substitute it into the equation y = mx + c.
y = mx + c
4 = 3x + c
4 - 3 = c
c = 1
The first number in your coordinate is your x value and the second is your y value. (x,y)

Does it matter which points you use to find the slope?
No. If you have more than two points for a linear function any two points can be used to find the slope.
What would the equation of a line be if it went through the point 2 comma 2 and its yintercept was 10?
We know that the line passes through points (2, 2) and (0, 10) (since the y-intercept is 10).Using these two points, we can find the slope of the line,m = (10 - 2)/(0 - 2) = 8/-2 = 4/-1 = -4.Now by using the slope, m = -4, and the y-intercept, 10, we can write the equation of the line in the slope-intercept form, y = mx + b which isy = -4x + 10.
What is a slope used for?
It shows the relationship of y in terms of x. [y = (yIntercept) + ((slope)*(x))] [slope = (y2 - y1)/(x2 - x1)]
To find the distance between any two points in the planes do you distance formula?
Yes
How do you find the rate of change between two points?
For two points at (x1,y1) and (x2,y2), respectively, the rate of change is equal to the slope of the shortest possible line segment connecting the two points. This slope can be calculated by the following equation: m = (y2-y1)/(x2-x1)
Does it matter which points you use to find the slope?
No. If you have more than two points for a linear function any two points can be used to find the slope.
Graphs how to find rule when given two points on graph?
Connect the two points.
How do you find out if two points have equal elevation?
The best way to find out if 2 points have equal elevation is to measure them. You must measure each of these points.
How do you find the angle between two points?
You have to convert them to Polar Points or the Azimuth points and use the angle difference.
If a segment connecting two points is horizontal you can find the distance between the points by?
When a line segment connecting two points is horizontal the length of the segment can be found by finding the absolute value of the difference in x-coordinates of the two points.
How to find out if two sets of points are collinear need help for geometry?
If the points are on the same line then are collinear.
What would the equation of a line be if it went through the point 2 comma 2 and its yintercept was 10?

How do you find the included angle?
The common vertex between two points
How do you find the diameter of a circle when you have two endpoints?
Measure the distance between the two end points!
Find the length of arc ABC?
Any variables to help us out? What points are ABC? Why are there three points for a curved line (something that has two points)?
What is the slope and yintercept of y plus 4x plus 3?
There is no slope nor intercept because there is no equation, simply an expression.
What is the slope of a line passing through the two points - Round your answer to the nearest tenth?
That depends on the points in order to find the slope whereas no points have been given.
