Answer:

slope is undefined
Explanation:
WE need to find the slope of two lines
to find out slope we use formula

To find slope we pick two points from the line
(-4,0) and (0,1) is (x1,y1) and (x2,y2)


To find slope we pick two points from the line
(1,0) and (1,1) is (x1,y1) and (x2,y2)

When denominator =0 then the slope is undefined
