Question

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

Answer 1

–x + 4y = –1

x – 4y = –1

x + y = 3

x – y = –3

Answer 2

@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:
\[x+y=3\]

Answer 3

Ohh okay thank you! I get it now

Answer 4

@heyitsmelalala You're welcome. :)
