Find an equation oif the line that contains the two points. Write the equation in the general form Ax+By+C=0.
(5,4)and(2,5)
Can anyone please teach me how to do this???
I got no idea with writing the equation in the general form.

There is two points given (5,4)&(2,5)
find slope, m = (54)/(25)
=9/7
y=mx +b
4=(9/7)(5) +b
b=17/7
y=(9/7)x +(17/7)
7y =9x 17
9x+7y+17=0
