graph{y=3x-4 [-10, 10, -5, 5]}

Explanation:

y = 3x -4

The minus four is where you start the line on the y axis, while the 3x tells you how far you go up per one across the x axis.

Look at explanation for how.

Explanation:

Okay, so the slope of the line is 3, which means that every 1 unit you move to the right (x-axis) you move up 3 (y-axis). You also have a y-intercept (also called a vertical shift) of negative 4. In a normal graph without the shift, you would start at (0,0), but since you have it your graph starts at (0,-4). After this point, your next one would be (1,-1), then (2,2), and so on and so forth.
