Line 1: zero

Line 2: negative

Line 3: undefined

Line 4: positive

Step-by-step explanation:

Line 1 => slope is horizontal. The slope of horizontal lines are always equal to 0. Therefore, the slope of line 1 is zero.

Line 2 => the line slants downwards form our left to the right, this implies there is a decline or increase. Thus, the slope would be negative.

Line 3 => the line of a vertical line is always undefined. Line 3 slope is therefore undefined.

Line 4 => the slope slants upwards from our left to the right. This indicates a rising slope or an increase. Therefore, the slope of line 4 is positive.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

it could be 1,3 and more others to create a cylinder.
