How To Find The Gradient From A Straight Line? You`re Given Coordinates From Point A And B

Q. Find the Gradient of this straight line , using the coordinates from point A (5,3) and point B (8,9) .

The equation that should come to our mind is :

m= Y₂-Y₁/X₂-X₁

_{m is referred as the gradient}

_{So using our coordinates A(5,3) and B (8,9)}

_{Let`s substitute them in the equation}

_{m = 9-3/8-5 = 6/3}

_{m= 2}

_{So, we have found out that our gradient is 3 ,but how do we put it in an equation?}

_{Now you have to remember the general form of a straight line equation Y= mX+C}

_{Here m is referred as gradient and C is your y- intercept - X and Y are the coordinates.}

_{So our equation would be :}

_{Y = 3X +C}

_{You don`t need to find the value of C unless they ask you to :) .}
