Answer:
y = 4x + 1
Explanation:
To get from the first point to the second one, you need to move to the right 1 unit and up 4 units. This makes the slope 4/1 which is just 4.
The y intercept is where the line passes through the y axis. This is at (0, 1).
When you put this all together, you get y = 4x + 1.
