Answer:

-2/3

Step-by-step explanation:

Well, you could use the equation y2-y1/x2-x1    y2=1 and y1=3   so 1-3 is -2. Then we know that x2 = 2 and x1 = -1  so we have 2-(-1) which is 3. Now we have -2/3.

Hi, there.

  _______

[tex]\text{Formula: }\bold{\dfrac{y_2-y_1}{x_2-x_1}}[/tex]

Now substitute the known parameters.

[tex]\bold{\dfrac{\hfill\stackrel{y_2}{\overbrace{1}}-\hfill\stackrel{y_1}{3}}{\hfill\stackrel{x^2}{2}-\hfill\stackrel{x_1}{(-1)}}}}[/tex]

[tex]\bold{\dfrac{-2}{3}}[/tex]

[tex]-\bold{\dfrac{2}{3}}[/tex]

Hope the answer - and explanation - made sense,

happy studying!!!
