y = x + 2

Step-by-step explanation:

Given

The attached graph

Required

Determine the equation

First, pick any 2 corresponding coordinates

(x_1,y_1) = (0,2)

(x_2,y_2) = (6,8)

Next, calculate the slope (m)

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{8-2}{6-0}$

$m = \frac{6}{6}$

m =1

The equation is calculated as:

y - y_1 = m(x - x_1)

Where:

(x_1,y_1) = (0,2) and m =1

y - 2 = 1(x - 0)

y - 2 = (x - 0)

y - 2 = x

Make y the subject

y = x + 2
