Answer:
The equation of line is y=x+3.
Explanation:
Consider the provided graph.
The slope intercept form of a line is:
y=mx+c
Where m is the slope and c is the y intercept.
y-intercept is a point where the value of x is 0.
From the provided graph we can identify the y intercept of the line is 3. Because at (0,3) the value of x is 0.
Now find the slope of line as shown

Here for 1 unit of run the graph rise 1 unit, thus the slope of the line is:

Now substitute the value of m and c in the slope intercept form.
y=x+3
Hence, the equation of line is y=x+3.
