Answer:
y = 4x -3
Explanation:
y = mx + b
The m is the slope and the b is the y-intercept.
The slope is 4/1 or just 4. If you start at the point (0,-3), you see that you need to go straight up 4 units and 1 unit to the right to get back on the line. That is a slope of 4/1 or just 4.
The y-intercept is where the line crosses the y axis. It crosses at (0,-3), so the y-intercept is -3.
