Answer:

y=3x-4

Explanation:

The slope of the line is 3/1, 3 being the rise and 1 being the run. That's how you know that 3 is always going to be multiplied by x.

The -4 part is found by seeing where the line intersects with the y axis. Since the line crosses the y axis at -4, the equation will include -4.
