10. Which of the following is the equation of a line that passes through (-2,-1) and (-4,-3)?
A. y=2x+1
B. y=x+1
C. y=2x-1
D. y=x-1

B) y=x+1

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-3-(-1))/(-4-(-2))

m=(-3+1)/(-4+2)

m=-2/-2

m=1

y-y1=m(x-x1)

y-(-1)=1(x-(-2))

y+1=(x+2)

y+1=x+2

y=x+2-1

y=x+1

Step-by-step explanation:

hello : answer B

because : when  x= -2  y= -2+1=-1

                 when : x=-4   y=-4+1 = -3

answer: the correct one is a
