Answer: [tex]y=-x-5[/tex]

Step-by-step explanation:

Slope intercept form is [tex]y=mx+b[/tex], so we have to find a way to substitute the given information into the equation. We have [tex]m[/tex] because it gives us the slope.  The slope is -1, as the directions state. Now, we substitute it in and solve for b:

  1. Substitute -1 in for m⇒ [tex]y=-x+b[/tex]
  2. Substitute in the point (-1, -4) in for [tex]x[/tex] and [tex]y[/tex] respectively to get [tex]-4=-(-1)+b[/tex]
  3. Solve the equation to get b= -5

After getting the y-intercept, you have the full equation!

The answer is A) y=-x-5

Hope this helps!
