$\frac{7}{9}$
$\frac{1}{2}$

解題步驟

  1. Understand the question

    encuentra la pendiente de: (1,8) y (3,12)
    2
    -2
    $\frac{7}{9}$
    $\frac{1}{2}$

  2. Explanation

    Step1: Recall slope formula

    The slope $m$ between two points $(x_1,y_1)$ and $(x_2,y_2)$ is $m=\frac{y_2-y_1}{x_2-x_1}$

    Step2: Assign point values

    Let $(x_1,y_1)=(1,8)$ and $(x_2,y_2)=(3,12)$

    Step3: Substitute into formula

    $m=\frac{12-8}{3-1}=\frac{4}{2}=2$

  3. Final answer
