Respuesta :

[tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{4 - 2}{3 - 1} = \frac{2}{2} = 1[/tex]
The answer is B.

y - y₁ = m(x - x₁)
 y - 2 = 1(x - 1)
 y - 2 = 1(x) - 1(1)
 y - 2 = x - 1
   + 2      + 2
      y = x + 1

Answer:

1.

Step-by-step explanation:

The formula of slope is: for two points (x1,y1) and (x2,y2) the slope is given by m = [tex]\frac{y2-y1}{x2-x1}[/tex]

So, for P and Q we have that the slope is m = [tex]\frac{4-2}{3-1}[/tex] = [tex]\frac{2}{2}[/tex] = 1.

So, the answer is 1.
