Part a

we have the points (3,7) and (3,-4)

Note that the x-coordinates are equal

that means

Is a vertical line (parallel to the y-axis)

that means

the slope is undefined

Verify

m=(-4-7)/(3-3)

m=-11/0 ----> undefined

Part b

we have the points (-2,5) and (9,5)

Note that the y-coordinates are equal

That means

Is a horizontal line (parallel to the x-axis)

The slope is zero

Verify

m=(5-5)/(9+2)

m=0/11

m=0
