Question

will fan and medal if you help please? :)

What is the equation of the following line written in general form?
(4,5)
(1,2)

y - x + 1 = 0
x - y + 1 = 0
-x - y + 1 = 0

Answer 1

x-y+1=0

Answer 2

first put it into point-slope form using a specific point, i chose (4,5). So y-5=m(x-4). I got m (the slope) and inserted it into the equation to get: y-5=1(x-4). Solve that to get it in standard form.
