The Answer is D

The first line has the slope of +1

[tex]m\text{ =(y2-y1)/(x2-x1) = (5-3)/(1+1)= 1}[/tex]

It has the y-intercept of 4 from the graph

[tex]y\text{ = x+4}[/tex]

The second line has the slope of -2

[tex]m\text{ = (4+2)/(-4+1) = 6/-3 = -2}[/tex]

It has the y-intercept of -4

[tex]y\text{ = -2x-4}[/tex]
