Online Slope Factor

Introduction :

Learning online slope factor is very simple and interesting. All linear equation has a slope factor which is attached with its x component. In general slope factor is represented by a symbol 'm'. Linear equation can be expressed as a relation between x and y with unit power. We can see linear equation in following forms:

ax + by + c = 0      ....................(1)

ax + by = c            .....................(2)

y = mx + b            ......................(3)

The equation y = mx + b is known as slope intercept form. where m is called slope factor and b is called y intercept. We can convert any linear equation in slope intercept form and then we can calculate slope factor. Slope factor is nothing but coefficient of x in the slope intercept form equation.

I like to share this System of Linear Equation with you all through my article.

eq 1 can be rewritten as: by = -ax -c   or y = (-a/b) -c/b

Therefore slope m = (-a/b)

Similarly, we can see that for eq 2 also slope m = (-a/b)

Slope or gradient of a line describes its steepness, incline, or grade. A higher slope value indicates a steeper incline.

The slope is defined as the ratio of the "rise" divided by the "run" between two points on a line, or in other words, the ratio of the altitude change to the horizontal distance between any two points on the line. Given two points (x1,y1) and (x2,y2) on a line, the slope m of the line is

m=(y2-y1)/(x2-x1)

Through differential calculus, one can calculate the slope of the tangent line to a curve at a point.

The concept of slope applies directly to grades or gradients in geography and civil. Through trigonometry, the grade m of a road is related to its angle of incline theta by

m=tan(theta).

If we have two points then find the slope  using 1st formula.

If we give any equation then we can find dy/dx=function(x) where substitute x value the we get slope.

If we have any angle then we have to use slope(m)=tan(teta) where teta is the angle.

Examples to learn online slope factor


Example1: Find the slope of 4x + 3y = 5.

Solution: Converting it into slope intercept form we get,

y = (-4/3)x + 5/3, comparing it with y = mx + b we get,

Slope m = -4/3


Example 2: Find slope of line passing through (0,0) and (2,3).

Solution: Slope m = (y2-y1)/(x2-x1)

m = (3-0)/(2-0)

or slope m = 3/2
