Find the slope of the line passing through the points (9, 1) and (-3, -3). Describe the slope as positive, negative, zero, or undefined. The slope equals The slope is (select)​

Respuesta :

Answer:

Given points:-

  • (9,1)
  • (-3,-3)

We have to find slope =m

  • As we know that

[tex]{\boxed{\sf Slope_{(m)}=\dfrac {y _2-y_1}{x_2-x_1}}}[/tex]

  • Substitute the values

[tex]\qquad {:}\longrightarrow\sf m=\dfrac {(-3-1)}{(-3-9)}[/tex]

[tex]\qquad {:}\longrightarrow\sf m=\dfrac {-4}{-12}[/tex]

[tex]\qquad {:}\longrightarrow\sf m={\dfrac {1}{3}}[/tex]

[tex]\therefore\sf Slope\;of\;the\:line=\dfrac {1}{3}(undefined)[/tex]
