Find the slope of the line determined by the given points. (2 points each)

1. (4, -5) and (-2, -8)

[tex]m=\frac{y^{2}-y^{1} }{x^{2}-x^{1} }\\\\m=\frac{-8-(-5) }{-2-(4)}\\\\m=\frac{-3}{-12}\\\\m=\frac{1}{4}[/tex]

2. (0, 0) and (-6, 9)

[tex]m=\frac{y^{2}-y^{1} }{x^{2}-x^{1} }\\\\m=\frac{-6-0}{9-0}\\\\m=\frac{-6}{9}\\\\m=-\frac{2}{3}[/tex]

3. (-3, 9) and (4, 2)

[tex]m=\frac{y^{2}-y^{1} }{x^{2}-x^{1} }\\\\m=\frac{9-2}{2-(-3)}\\\\m=\frac{7}{5}[/tex]

4. (13, -10) and (24, 36)

[tex]m=\frac{y^{2}-y^{1} }{x^{2}-x^{1} }\\\\m=\frac{36-(-10)}{24-13}\\\\m=\frac{46}{11}[/tex]

Note: Use the equation [tex]m=\frac{y^{2}-y^{1} }{x^{2}-x^{1} }[/tex] to find the slope when you have two points given.
