Please solve the picture below
Complete the equation

y - 2  = -2x

Step-by-step explanation:

A point slope equation is of the form;

          y  = mx + c

c is the y intercept

y and x are coordinate values

m is the slope

        y - c = mx  is similar to the given problem,

         y -2  = ?

We need to find mx;

  m is the slope;

Given coordinates;

     (6,4) and (7,2)

x₁ = 6

y₁ = 4

x₂ = 7

y₂ = 2

Slope of a line  =

Insert the parameters and solve;

   Slope of the line  =   = -2

So,

                               y - 2  = -2x
