What is the equation in standard form of the line which passes through (–2, 6) and has a slope of –1?

x + y = –4
x + y = 4
x –y = –4
x –y = 4

Oh, I'm sorry I can't help I'm only in 7th grade and I'm dumb at math

mathmale · Answer

You are given a point through which your line passes, as well as the slope of the line.  Use the "point-slope formula for the equation of a straight line:"

$$y-y _{1}=m(x-x _{1}).$$

mathmale · Answer

The given point is (-2,6).  Thus, let x1=-2 and y1=6.  Also substitute m=-1.

mathmale · Answer

that's the main work.

The "standard form of an equation of a str. line" is Ax+By+C=0 or Ax+By=D.

Once you have your first equation, re-write it in the above form to finish this problem.

Okay thank you!  Ill write it down now

anonymous · Answer

so y-6=-1x-(-2) would that be were I would start and just continue solving from there?
