Write the equation of the line that passes through (–1, 4) with a slope of –1 in standard form.

Question

anonymous · Answer

–x + 4y = –1

 x – 4y = –1

 x + y = 3

 x – y = –3

@heyitsmelalala You can use the point-slope form to know the equation.
$$(y-y _{1})=m(x-x _{1})$$
$$(y-4)=(-1)(x+1)$$
Distribute -1.
$$y-4=-x-1$$
Transpose -4:
$$y=-x+3$$
You may say, "Those aren't on the choices" but in fact, they are. You just need to twist those choices and you'll see that the answer is:
$$x+y=3$$
