Answer:
y = (-1/4)x-5/4
Step-by-step explanation:
Coordinate Points (7,-3) and (-1,-1)
m = change in y/ change in x = -1−(-3)/-1−7
=-1+3/-1−7
=-2/8
=-1/4
y = mx + b
y = (-1/4)x +b *********** (1)
substitute x=-1, y=-1
y = (-1/4)x +b
-1=(-1/4)(-1)+b
b=-1-1/4
b=-5/4
substituting b into (1)
y = (-1/4)x-5/4
