What is the formula used to find slope?
The slope of a straight line equation is: y2-y1/x2-x1
What is the slope of the line that goes through the points 2 5 and 1 -3?
To solve this, use the slope formula. the slope formula is m = (y2 - y1) / (x2 - x1) Therefore, m = ( -3 - 5)/ (1-2) If you solve this, you will get 8. So the slope of the line is 8.
What do you need to use the point slope formula?
The slope of a line and the coordinates of a point on the line.The slope of a line and the coordinates of a point on the line.The slope of a line and the coordinates of a point on the line.The slope of a line and the coordinates of a point on the line.
How do you find the equation of a line if you know the slope and y-intercept?
The formula for finding a line when the slope and y-intercept are known is as follows:y = mx+bm is the slopeb is the Y-interceptJust substitute the slope for m and the Y-intercept for b.
When was the slope formula for geometry invented?
Mathematicians would say that Renee Descartes, the "Father of Analytical Geometry," is acknowledged as the discoverer of the formula (1596-1650), though there are little write ups on this formula.
