Explanation:

Step1: Recall slope - intercept form

The slope - intercept form of a line is $y = mx + b$, where $m$ is the slope and $b$ is the y - intercept.

Step2: Find the y - intercept

The y - intercept is the point where the line crosses the y - axis. From the graph, the line crosses the y - axis at $(0,-2)$, so $b=-2$.

Step3: Calculate the slope

The slope $m$ is calculated using the formula $m=\frac{y_2 - y_1}{x_2 - x_1}$. Let's take two points on the line, for example, $(0,-2)$ and $(1,0)$. Then $m=\frac{0 - (-2)}{1 - 0}=\frac{2}{1}=2$.

Step4: Write the equation

Substitute $m = 2$ and $b=-2$ into the slope - intercept form $y=mx + b$. We get $y = 2x-2$.

Answer:

$y = 2x-2$
