Find
Now select one point and apply the point-slope formula.
Hi, what is the best way to find the equation of a straight line when given to points on the line. ie (x1,y1) and (x2,y2)
I have been finding the gradient m=y2-y1/x2-x1 and then putting into the formula y-y1 =m(x-x1) but i am doing something wrong as i keep getting different answers to my textbook. Could somebody please solve one for me so i can see how it's done?
Heres one in my book Find the equation of the line AB when A(-2,4) B(5,3)
Thanks, Chris.
