Question

This is slope intercept form equation question.

Answer 1

Answer:

The answer to your question is y = x

Step-by-step explanation:

Data

A (1 , 1)

B (2, 2)

Process

1.- Find the slope (m) of the line

   m = (y2 - y1) / (x2 - x1)

x1 = 1     y1 = 1

x2 = 2   y2 = 2

- Substitution

   m = (2 - 1) / (2 - 1)

   m = 1 / 1

- Result

    m = 1

2.- Find the equation of the line

    y - y1 = m(x - x1)

- Substitution

    y - 1 = 1(x - 1)

- Simplification

   y - 1 = x - 1

   y = x - 1 + 1

- Result

   y = x
