Answer:

Explanation:

The slope formula states that the slope of the line between two points (x1,y1) and (x2,y2) is given by

m=y2−y1x2−x1

If we let (0,−9) be point 1, and (−5,−1) be point 2, then

x1x2=0=−5y1y2=−9=−1

Substituting these values into the slope equation and simplifying gives

m=y2−y1x2−x1=−1−(−9)−5−0=8−5=−8/5

Answer:

-4

Explanation:

  1. You have to get both of the points (0,-9) and (-5,-1) and divide them by their rise/run which is equivalent to slope.
  2. So.....
  3. We start on top with -5--9/-1-0= 4/-1
  • This makes the slope -4 when it is divided
  • I hope I helped you!!! remember the formula is the horizontal/vertical length.
