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
