Question

Write an equation of the line that

passes through (7,-3) and
(-1,-1). Put your answer in
standard form.

Answer 1

y = (-1/4)x-5/4

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
