Answer:
y = x + 3
Explanation:
To find the equation of the line, you need the slope-intercept formula.
y = mx + b is the slope-intercept formula and m is the slope, and b in the y intercept of the line. To find the slope, you find the difference in y between two points over the difference in x between the same two points. For this question, it is 1/1. 1 change in y for every 1 change in x, so the m is equal to 1. To find b, you just look where the line crosses the y line. In this line, it crosses at y = 3, so b is 3. x should just stay as it is so the final equation is
y = 1x + 3 or y = x + 3
