Question

Which of the following is the equation of a line passes through (-2,-1) and (-4,-3)?

a. y=1/2 x+1
b.y=x+1 i pick this one
c.y=1/2 x-1
d.y=x-1

Answer 1

b is correct

Answer 2

how do u know

Answer 3

the coordinates are in the form (x,y), so plug in the values
y=x+1
-1=-2+1
-1=-1

Answer 4

slope= change in y over change in x

Answer 5

\[\frac{-2-(-4)}{-1-(-3)}=\frac{2}{2}=1\]
y=mx+b
y=1x+b
y=x+b
-1=-2+b
-1+2=b
1=b
y=x+1

Answer 6

\[slope=\frac{y1-y2}{x1-x2}\]

Answer 7

Just follow Myininaya from there :)
