Answer:
y = 2x+3
Explanation:
The slope is "what happens to the graph when you move one unit to the right in x-direction". As you can check, if you move 1 to the right, the y value increases by 2. Therefore the slope is 2.
The intercept is the graph's y value when x=0, ie., when it passes the y axis. This is at y=3.
Now we have our two ingredients, so y = slope * x + intercept, so 2x+3
