Answer:
Step-by-step explanation:
37) Take two point from the line.
(2 , 0) & (0,4)
[tex]Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{4-0}{0-2}\\\\=\frac{4}{-2}\\\\=-2[/tex]
Slope = (-2)
38) (7 , 0) & (3 , 2)
[tex]Slope = \frac{2-0}{3-7}\\\\=\frac{2}{-4}\\\\=\frac{-1}{2}[/tex]
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
