A line passes through the points (-1,-4) and (-2,0). What is the equation of this line?
1 answer:
Answer:
y = -4x -8
Step-by-step explanation:
The slope is given by
m = (y2-y1)/(x2-x1)
m = (0--4)/(-2--1)
= (0+4)/(-2+1)
=4/-1
= -4
We know the point slope form of a line is
y-y1 = m(x-x1)
y-0 = -4( x--2)
y = -4(x+2)
y = -4x -8
