Answer:

The answer to your question is the letter C)     y = 1/2x+ 1      

Step-by-step explanation:

Data

Point 1 = (2, 2)

Point 2 = (-4, -1)

Process

1.- Find the slope of the line

Slope = m = (y2 - y1)/(x2 - x1)

      x1 = 2   y1 = 2   x2 = -4   y2 = -1

-Substitution

             m = (2 + 1) / (2 + 4)

-Simplification

             m = 3/6

-Result

             m = 1/2

2.- Find the equation of the line

             y - y1 = m(x - x1)

             y - 2 = 1/2(x - 2)

-Expand

             y - 2 = 1/2x - 2(1/2)

-Simplify

            y - 2 = 1/2x - 1

            y = 1/2x - 1 + 2

-Result

             y = 1/2x+ 1
