Question

Answer all of these for 100 points

Answer 1

39) The line is parallel to x-axis and so its slope is 0

Slope = 0

40) The line is parallel to y-axis and so its slope is undefined

Slope = undefined

Explanation:

Answer 2

Explanation:

37) Take two point from the line.

(2 , 0) & (0,4)

`Slope = (y_(2)-y_(1))/(x_(2)-x_(1))\\\\=(4-0)/(0-2)\\\\=(4)/(-2)\\\\=-2`

Slope = (-2)

38) (7 , 0) & (3 , 2)

`Slope = (2-0)/(3-7)\\\\=(2)/(-4)\\\\=(-1)/(2)`

39) The line is parallel to x-axis and so its slope is 0

Slope = 0

40) The line is parallel to y-axis and so its slope is undefined

Slope = undefined
